These disorder can cause disturbance of the heart rate, the heart rhythm, or both. Named according to the site of origin of the impulse and the mechanism of formation or conduction involved. CAUSES OF DYSRHYTHMIAS Electrolyte Imbalances Ischemia or Myocardial Infarction (Heart Attack) Heart Failure Structural Heart Disease Medications and Drugs Stress and Stimulants Hyperthyroidism Conduction System Disorders Infections and Inflammation Genetic Disorders Autonomic Nervous System Imbalances  TYPES OF DYSRHYTHMIAS SINUS TACHYCARDIA The rhythm still originates at the SA node but at an increased rate of greater than 100 beats per minute for both the atria and ventricles. The heart rate is usually between 100 and 120 beats per minutes. CAUSES: medication, exercise, anxiety, fever, anemia, heart failure and hypovolemia MANAGEMENT: Carotid sinus pressure (carotid massage) or Beta-blockers SINUS BRADYCARDIA The rhythm still originates at the SA node but a decreased rate of less than 60 beats per minute for both the atria and ventricles. CAUSES: Medication, vagal stimulation, hypoendocrine states and hypothermia MANAGEMENT: Anticholinergic drugs like atropine sulfate  PREMATURE ATRIAL CONTRACTION Ectopic beats that originates from the atria and they are not rhythms. Cells in the heart starts to fire or go off before the normal heartbeat is supposed to occur. These called heart palpitations. CAUSES: Coronary or valvular heart diseases, atrial ischemia, coronary artery atherosclerosis, heart failure, COPD, electrolyte imbalance and hypoxia. MANAGEMENT: Procainamide and quinidine and carotid sinus massage ATRIAL FLUTTER An abnormal rhythm that occurs in the atria of the heart. Atrial flutter has an atrial rhythm that is regular but has an atrial rate of 250 to 400 beats/min. It has sawtooth appearance. QRS complexes are uniform in shape but often irregular in rate. CAUSES: Heart failure, tricuspid valve or mitral valve disease, pulmonary embolism, inferior wall MI, carditis and digoxin toxicity. MANAGEMENT: Cardioversion, calcium channel blocker, beta-adrenergic blockers and anticoagulant ATRIAL FIBRILLATION Results from abnormal impulse formation that occurs when structural or electrophysiological abnormalities alter the atrial tissue causing a rapid, disorganized, and uncoordinated twitching of the atrial musculature. CAUSES: Atherosclerosis, heart failure, congenital heart disease, chronic obstructive pulmonary disease, hypothyroidism and thyrotoxicosis.  PREMATURE JUNCTIONAL CONTRACTION Occurs when some regions of the heart become excitable than. PR interval less than 0.12 seconds if P wave precedes QRS complex QRS complex configuration and duration is normal P wave is inverted Atrial and ventricular rhythms irregular CAUSES: Myocardial infarction, digoxin toxicity, excessive caffeien or amphetamine use.  ATRIOVENTRICULAR BLOCKS Av blocks are conduction defects within the AV junction that impairs conduction of atrial impulses to ventricular pathways First Degree AV Block The electrical impulses from the atria are delayed as they pass through the AV node, but eventually all impulses reach the ventricles. This is the mildest form of AV block. Prolonged PR interval (>0.20 seconds) CAUSES: MI, hyperkalemia, hypokalemia, digoxin toxicity, calcium channel blockers, amiodarone and use of antidysrhythmic Second Degree AV Block There are two subtypes of second-degree AV block: Mobitz Type I (Wenckebach Block) Progressive delay in AV node conduction until one impulse fails to pass through, resulting in a dropped QRS complex. Progressive lengthening of the PR interval until a P wave is not followed by a QRS complex (dropped beat). After the dropped beat, the cycle repeats. Mobitz Type II Some of the atrial impulses fail to conduct to the ventricles, without a progressive lengthening of the PR interval. It is more dangerous than Type I and can progress to a complete block. Intermittent dropped QRS complexes without PR interval lengthening. PR intervals remain constant when the conduction occurs. Third Degree Block Complete failure of the electrical impulses to pass from the atria to the ventricles. The atria and ventricles beat independently of each other, causing severe disruption of the heart’s function. Atrial rhythm regular Ventricular rhythm regular and rate slower than atrial rate No relation between P waves and QRS complexes NO constant PR interval PREMATURE VENTRICULAR CONTRACTIONS Early heartbeats that originate in the ventricles rather than from the sinoatrial (SA) node, which is the normal pacemaker of the heart. PVCs are a type of ventricular arrhythmia. CAUSES: Myocardial infarction (heart attack), heart failure, electrolyte imbalances, and drug toxicity. MANAGEMENT: Beta-blockers (metoprolol) and Calcium Channel Blockers: (verapamil)  VENTRICULAR TACHYCARDIA A type of ventricular arrhythmia where the ventricles (the lower chambers of the heart) beat very fast, usually at a rate of 100 to 250 beats per minute. It is considered a medical emergency because cardiac output cannot be maintained because of decreased diastolic filling (preload). CAUSES: MI, aneurysm, CAD, rheumatic heart diseases, mitral valve prolapse, hypokalemia, hyperkalemia, pulmonary embolism and anxiety.  VENTRICULAR FIBRILLATION Ventricular fibrillation is rapid, ineffective quivering of ventricles that may be rapidly fatal. CAUSES: Myocardial ischemia, electrolyte imbalances, digoxin toxicity or hypothermia  SIGNS AND SYMPTOMS Chest pain or tightness Dizziness or lightheadedness Fainting Palpitations – a feeling of skipped heartbeats or fluttering Pounding in the chest Shortness of breath Weakness or fatigue PATHOPHYSIOLO GY MEDICAL MANAGEMENT Electrocardiogram (ECG or EKG) A diagnostic tool that records the electrical activity of the heart over a period of time using electrodes placed on the skin. It provides a visual representation of the heart's electrical impulses, which are crucial in regulating the heart's contractions. Holter Monitor A portable device used to continuously record the heart's electrical activity over 24 to 48 hours or longer, depending on the prescription. Holter monitor tracks heart rhythms for a longer period while the person goes about their daily activities. MEDICAL MANAGEMENT Echocardiogram A non-invasive imaging technique that uses ultrasound waves to create real-time images of the heart. It provides valuable information about the heart's structure and function, including its chambers, valves, and blood flow. Tilt Table Test A diagnostic procedure used to evaluate the cause of unexplained fainting and assess how a person's heart and blood pressure respond to changes in body position. MEDICAL MANAGEMENT Stress Test (Exercise ECG) A diagnostic procedure that evaluates how the heart responds to physical stress or exercise. The test typically involves monitoring the heart's electrical activity while the patient exercises on a treadmill or stationary bike. Blood Tests A medical diagnostic procedure that involves analyzing a sample of blood to provide information about a person's health. Check for conditions like electrolyte imbalances or thyroid dysfunction that may cause arrhythmias.  PHARMACOLOGICAL MANAGEMENT Sodium Channel Blockers (Class I) These medications work by blocking sodium channels in the heart, which helps to slow down electrical conduction and reduce abnormal impulses. Beta-Blockers (Class II) These medications block the effects of adrenaline and reduce the heart's workload, slowing the heart rate and decreasing the force of contraction. Potassium Channel Blockers (Class III) These medications prolong the repolarization phase of the heart’s electrical cycle by blocking potassium channels, which stabilizes the  PHARMACOLOGICAL MANAGEMENT Calcium Channel Blockers (Class IV) These medications slow down the conduction through the atrioventricular (AV) node by blocking calcium channels, helping to control heart rate. Anticoagulants Prevent blood clots and reduce stroke risk in patients with atrial fibrillation, especially those with other risk factors like heart failure, hypertension, or diabetes. Electrolyte Supplements Low levels of certain electrolytes, particularly potassium and magnesium, can trigger or worsen arrhythmias. Electrolyte  SURGICAL MANAGEMENT Pacemaker Implantation A procedure to put a small battery- operated device called a pacemaker into your chest. The pacemaker sends regular electrical impulses, which help keep your heart beating regularly. Maze Procedure A surgical technique used primarily to treat atrial fibrillation (AFib). The procedure involves creating a series of precise incisions (or "maze") in the atrial tissue to disrupt the abnormal electrical pathways that cause AFib.  SURGICAL MANAGEMENT Coronary Artery Bypass Grafting (CABG) This surgery improves blood flow to your heart by creating a bypass around your narrowed coronary arteries using arteries or veins taken from other parts of your body.  LABORATORIES Complete Blood Count (CBC): Check for anemia or signs of infection (elevated white blood cell count). normal range : Hemoglobin: Men: 13.5–17.5 g/dL Women: 12.0–15.5 g/dL Hematocrit: Men: 38.8%–50.0% Women: 34.9%–44.5% White Blood Cell Count (WBC): 4,500–11,000 cells/mcL  LABORATORIES Thyroid function tests to check for hyperthyroidism TSH -.35 to.50 TT4- 6-12 ug/d FTI- 4.6-10.9 mg/dl FT4- 0.7-1.53 ng/dL Resin T3 Uptake- 24-39 md/dl FT3- 260-480 pg/mL  LABORATORIES Basic metabolic panel (BMP) to look for Kidney function to access for electrolyte abnormalities kidney injury Electrolytes: Monitor levels of sodium, Renal Function Tests: serum potassium, calcium, and magnesium, as creatinine and blood urea imbalances can affect cardiac function. nitrogen (BUN) to assess kidney Normal range : function.
