Electrocardiogram Interpretation

Basic Components:

- QRS complex: Ventricular depolarization
- T wave: Ventricular repolarization
Key Patterns:
- Sinus rhythm: Normal heart rhythm
- Atrial fibrillation: Irregularly irregular rhythm
- ST elevation: Indicative of myocardial infarction
- ST depression: Suggests ischemia
Axis Deviation:
- Left Axis Deviation (LAD)
- Right Axis Deviation (RAD)

Cardiac Pharmacology

Key Drug Classes:
- Antihypertensives: ACE inhibitors, ARBs, calcium channel blockers, diuretics
- Anticoagulants: Warfarin, direct oral anticoagulants (DOACs)
- Antiplatelets: Aspirin, clopidogrel
- Statins: For cholesterol management
- Heart Failure Medications:
  - SGLT2 inhibitors
  - ARNI (Angiotensin Receptor-Neprilysin Inhibitor)

Interventional Cardiology

Procedures:
- Angioplasty and Stenting: Open narrowed arteries
- Coronary Artery Bypass Grafting (CABG): Bypass blocked arteries
- Balloon Valvuloplasty: For valvular stenosis
- Transcatheter Aortic Valve Replacement (TAVR): Minimally invasive heart valve surgery
Indications:
- Acute coronary syndrome
- Severe coronary artery disease

Acute Coronary Syndrome (ACS)

Definition: A spectrum of conditions associated with sudden reduced blood flow to the heart.
Types:
- Unstable angina
- NSTEMI (Non-ST-Elevation Myocardial Infarction)
- STEMI (ST-Elevation Myocardial Infarction)
Symptoms: Chest pain, dyspnea, nausea, sweating
Management:
- Immediate medication (antiplatelets, anticoagulants)
- Risk stratification
- Possible intervention (PCI or CABG)

NSTEMI

Characteristics:
- Myocardial damage without ST elevation on ECG
- Elevated troponin levels
Management:
- Antiplatelet therapy (aspirin, clopidogrel)
- Anticoagulation
- Consideration for PCI based on risk stratification

STEMI

Characteristics:
- Complete occlusion of a coronary artery
- ST elevation on ECG
- Elevated troponin levels
Management:
- Immediate reperfusion therapy (PCI or thrombolytics)
- Dual antiplatelet therapy
- Beta-blockers and ACE inhibitors post-reperfusion

Hypertension

Definition: Persistently elevated blood pressure (≥ 130/80 mmHg).
Types:
- Primary (essential) hypertension
- Secondary hypertension (due to another condition)
Risk Factors: Age, obesity, family history, high sodium intake, sedentary lifestyle
Management:
- Lifestyle modifications (diet, exercise)
- Pharmacotherapy:
  - Thiazide diuretics
  - ACE inhibitors
  - ARBs
  - Calcium channel blockers
Monitoring: Regular blood pressure checks and management of comorbidities.

Heart Failure Management

Condition where the heart fails to pump adequately to sustain blood circulation.
Two primary types: HFrEF (reduced Ejection Fraction) and HFpEF (preserved Ejection Fraction).
Medications include ACE inhibitors, beta-blockers, diuretics, and aldosterone antagonists for heart function improvement.
Lifestyle modifications encompass low-sodium diets, fluid intake restrictions, and regular exercise to enhance overall health.
Devices such as implantable cardioverter-defibrillators (ICD) and cardiac resynchronization therapy (CRT) assist with heart rhythm and efficiency.
Surgery options consist of heart transplants and ventricular assist devices (VADs) for severe cases.

Electrocardiogram Interpretation

P wave represents atrial depolarization, QRS complex indicates ventricular depolarization, and T wave signifies ventricular repolarization.
Key patterns identified in ECG include sinus rhythm (normal), atrial fibrillation (irregular), ST elevation (myocardial infarction), and ST depression (ischemia).
Axis deviation can present as left axis deviation (LAD) or right axis deviation (RAD), indicating abnormal heart orientations.

Cardiac Pharmacology

Antihypertensives include ACE inhibitors, ARBs, calcium channel blockers, and diuretics, focusing on blood pressure regulation.
Anticoagulants like warfarin and direct oral anticoagulants (DOACs) are essential for preventing blood clots.
Antiplatelets, including aspirin and clopidogrel, are crucial in preventing thrombosis.
Statins are utilized for cholesterol management and reducing cardiovascular risk.
Heart failure medications such as SGLT2 inhibitors and ARNI (Angiotensin Receptor-Neprilysin Inhibitor) enhance heart failure treatment.

Interventional Cardiology

Angioplasty and stenting are procedures used to open narrowed coronary arteries.
Coronary Artery Bypass Grafting (CABG) is a surgical intervention to bypass blocked arteries.
Balloon valvuloplasty is performed for patients with valvular stenosis to increase valve opening.
Transcatheter Aortic Valve Replacement (TAVR) is a minimally invasive technique to replace damaged heart valves.
Indications for these interventions include acute coronary syndrome and severe coronary artery disease needing urgent treatment.

Acute Coronary Syndrome (ACS)

Refers to a range of conditions linked to abrupt reduction in blood flow to the heart.
Types include unstable angina, NSTEMI (Non-ST-Elevation Myocardial Infarction), and STEMI (ST-Elevation Myocardial Infarction).
Common symptoms are chest pain, dyspnea, nausea, and sweating.
Management strategies involve immediate antiplatelet and anticoagulant therapy, risk assessment, and potential interventions like PCI or CABG.

NSTEMI

Characterized by myocardial damage indicated by elevated troponin levels without ST elevation on ECG.
Management includes antiplatelet therapy (aspirin, clopidogrel), anticoagulation, and considering percutaneous coronary intervention (PCI) based on assessed risk.

STEMI

Identified by complete blockage of a coronary artery, ST elevation on ECG, and elevated troponin levels.
Immediate management requires reperfusion therapy through PCI or thrombolytics, followed by dual antiplatelet therapy and the use of beta-blockers and ACE inhibitors following reperfusion.

Hypertension

Defined as consistently elevated blood pressure readings (≥ 130/80 mmHg).
Two categories: primary (essential) hypertension and secondary hypertension (due to identifiable causes).
Risk factors include age, obesity, family history, high sodium intake, and sedentary behavior.
Management approaches involve lifestyle changes (diet and exercise) and pharmacotherapy with thiazide diuretics, ACE inhibitors, ARBs, and calcium channel blockers.
Regular monitoring of blood pressure and addressing comorbid conditions are essential for effective management.
