Study Notes

Cardiovascular System and Arrhythmias

  • Arrhythmias involve an abnormal heart rate and/or rhythm due to issues in the heart's electrical conduction system.
  • They are identified through ECG.

Heart Rate

  • Normal heart rate is 60-100 beats per minute (bpm).
  • Bradycardia is a heart rate below 60 bpm.
  • Tachycardia is a heart rate above 100 bpm.

Atrial Fibrillation (AF)

  • Paroxysmal Atrial Fibrillation involves AF episodes that resolve within 7 days, typically without intervention within 48 hours.
  • "Pill in pocket" refers to a patient self-managing paroxysmal AF by taking antiarrhythmic medication at the onset of an AF episode.
  • ARRHYTHMIA = A(Abnormal) R(Rate) & R(Rhythm).

Signs and Symptoms of Arrhythmias (S.A.D Palpitations)

  • Main symptoms include Shortness of breath, Abnormally fast, slow, or irregular pulse, Palpitations, Dizziness or feeling faint.

Causes of Arrhythmias

  • Common causes include Coronary Heart Disease, Heart Valve Disease, Hypertension, Ageing, Cardiomyopathy, and Congenital abnormalities.
  • Ectopic beats are extra heartbeats resulting from signals in the upper heart chambers.
  • Treatment for ectopic beats is typically unnecessary with a regular heart and reassurance for the patient.
  • Beta-blockers is an effective, safe treatment for ectopic beats that are particularly troublesome.

Treatment of Arrhythmias

  • Treatment options tailored to the specific arrhythmia, addressing underlying causes like hypertension and coronary heart disease.
  • Available treatments include Medications, Cardioversion (electrical shock), Artificial Pacemakers, and Implantable Cardioverter defibrillators (ICDs).
  • The goal is to reduce symptoms and prevent complications, particularly stroke, in patients with Atrial Fibrillation.

Stroke and Bleeding Assessments in AF

  • CHADS2-Vasc is used to measure the risk factors for stroke (including a history of ischaemic strokes, diabetes, hypertension, cardiovascular events, being female and aged over 65).
  • HAS-BLED is used to measure the risk factors for bleeding.
  • The ORBIT tool provides higher accuracy than other tools like HASBLED and ATRIA for assessing bleeding risk.

Anticoagulation

  • When the risk of stroke is greater than the risk of bleeding, anticoagulants to prevent stroke are administered.
  • A CHA2DS2-VASc score > 2 requires an anticoagulant.
  • No anticoagulants are necessary for males with a score = 0 and females with a score = 1.

HASBLED Risk Factors (THREE)

  • A score > THREE indicates HIGH risk of bleeding.
  • Don't give an anticoagulant unless they are already on an anticoagulant stop the medication or reduce the dose give an antidote.

ORBIT Tool Risk Factors

  • Risk factors include age over 74, reduced haemoglobin (anaemia), bleeding history, inadequate kidney function (GFR <60), and antiplatelet treatment.
  • 0-2 is LOW risk
  • 3 = MEDIUM risk
  • 4-7 = High risk

Drug Treatment for Atrial Fibrillation

  • First-line treatment (rate control) to lower heart rate is achieved by:
    • Diltiazem (unlicensed)
    • Digoxin
    • Verapamil
    • Beta-blockers (NOT sotalol)
  • Drug treatment is typically monotherapy, but combine if monotherapy fails.
  • Avoid calcium-channel blockers in Atrial Fibrillation with Heart Failure or give them a Beta Blocker.
  • Digoxin is given as monotherapy ONLY to people that do not exercise. Digoxin is used in Atrial Fibrillation with congestive Heart Failure

Rhythm Control Strategy

  • If monotherapy fails to adequately control ventricular rate, consider a combination with any TWO of the following Drugs that includes:
    • Beta Blockers
    • Digoxin
    • Diltiazem
  • RATE CONTROL is ALWAYS 1st line treatment for Atrial Fibrillation except in people:
    • Whose Atrial Fibrillation has a reversible cause
    • Who have Heart Failure thought to be primarily caused by Atrial Fibrillation
    • With New-Onset Atrial Fibrillation.
  • Rhythm control (restores sinus rhythm) achieved through pharmacological Electrical cardioversion (defibrillator).
  • First-line treatment to revert sinus rhythm is done using Beta Blockers (Not Sotalol as first line).

Acute Atrial Fibrillation

  • If you do not succeed with Beta Blockers, then use Flecainide or Amiodarone, other drugs used are Satalol, propafenone and dronodarone
  • Rhythm control (a return to normal heart rate and rhythm) is used for Atrial Fibrillation symptoms continue after heart rate has been controlled or who can't have rate control.
  • Sinus rhythm can be restored by electrical cardioversion or pharmacological cardioversion with antiarrythmic dugs, like Flecainide and Amiodarone Oral anticoagulation should be given AFTER cardioversion after 4 weeks. Acute Atrial Fibrillation is new onset AF in less than 48 horus- Emergency cardioversion may be needed for life-threatening and unstable patients
  • Oral anticoagulation: is given as first line or contraindicted then give Vit K antagnoist eg Warfarin.

Anti-Arrhythmic Agents

  • Supraventricular Arrhythmias use Verapamil, Adenosine, & Cardiac glycosides
  • Ventricular Arrhythmias use Lidocaine, Sotalol Supraventricular and Ventricular Arrhythmias use Amiodarone and Beta Blockers
  • Anti-arrhythmic drugs classified according to the electrical activity in the Vaughan Williams is ALL CHANNEL BLOCKERS
  • Class I membrane stabilising drugs, sodium Channel Blockers like Lidocane
  • Class II Beta Blockers
  • Class III Potassium Channel Blockers like Amiadarone which is also Class II.
  • Class IV Calcium Channel Blockers like Veramamil but not Dihydropyridines Causes of Torsade De Pointes includes stress, strenuous exercise, sudden noise, drugs, hypokalemia and bradycardia Treatment for Torasade de Pointes is I.V Magnesium Sulphate Examples of Drugs which prolong QT Interval (Anti-Arrhythmic):
  • Amiodarone
  • B-AntiBiotics
  • C-Antipsychotics
  • D-AntiDepressants
  • D-Diuretics
  • EAntiEmetics

Drug Interactions

  • Amioderone is used to treat Arrythmias, by blocking enzymes
  • 200 mg three times a day for the first week then reduced to 200mg twice a day for one week. Then followed by a intanence dose of 200mg. once Daily

Amiodarone Side Effects

  • Remember (AMI is a Photogenic BITCH):
    • Photosensitivity
    • Bradycardi
    • Interstitial lung disease
    • Thyroid -Iodine
  • Corneal micro deposits dazzled by headlights at night
  • Hepatic Liver toxicity- Discontinue
  • Optic neuropathy blind Stop vision
  • Peripheral neuropathy hands and feet -tingling and numbness in hands and feet
  • Phototoxicity
  • Pilmonary Toxicity Suspect pneumonitis if progressive shortness of breath or dry cough develop
  • Contraindication is Thyroid Dysfunction and lodine sensitivity

Monitoring Requirements

  • Remember CASTEL = Chest X-Ray annual eve tests, Serum postassium- Hypokalaemia thyroid
  • Liver test
  • E.C.G Intrevenous use & Blood Pressure Patient Carer Advice include Shield skin to prevent sun use wide-specrtrm sunscreen to seek medical treatmen

Digoxin

  • Increases heart rate and decreases heart rate by reducing conductivity in atriventriculafr node.
  • Useful in controlling ventricular in persistant Atrial Fibrilation
  • Use of atrial flutter in maintaing.Sinus rythm in Heart Failure The maintenance dose is determined as you d not fall below 60BPM long half-life

Dosing and Mechanism

  • The heart must not beat more than 48 hours, and not suitable used for rapid heart rate control Drug Interactions Remember 2kidneys use increasing force in reducing conductivity for treating irregular heart rate. Mechanism of Action

Tranexamic acid

  • inhibits fibrinolysis.
  • For epitasis the does is 19 THREE Tomes Day for 7 days
  • Administration: taken with or without food
  • Increased risk of DVT with conteracptive pill Red flag :
  • Colour vision change of visual impaired (Discontinue)
  • Coughing up blood
  • Anaphylactic reaction

Medications

  • Treat each according with the appropriate dose and time according to the condition.
  • Make note of the conditions when they are required.
  • Keep the patients medical record in mind when giving advice

Blood Pressure

  • Be sure to take blood pressure appropriately in order to diagnose pre-eclampsia using: - First Line-Oral Labetalol -Second Line – Modified Release Nifedipine (unlicensed) - Third Line Methyldopa (unlicensed)-Stop methyldopa TWO Days after birth and continue regular hypertension treatment.
  • If in critical care it can be treated via inter venial as well depending on a doctors assessment.
