Study Notes
Electrocardiography Basics
- Electrodes in electrocardiography detect the electrical activity of the heart, specifically the cardiac muscles' depolarization and repolarization.
- An electrocardiogram (ECG or EKG) represents the recording of the heart's electrical activity over a period of time, typically displayed as a graph of voltage versus time.
Purpose of Electrocardiography
- The purpose of electrocardiography is to diagnose and monitor various heart conditions, such as arrhythmias, coronary artery disease, and cardiac chamber enlargement.
Factors Affecting ECG Pattern
- Changes in the normal ECG pattern can be caused by various factors, including:
- Cardiac conditions, such as myocardial infarction, cardiac hypertrophy, or cardiomyopathy.
- Electrolyte imbalances, particularly potassium, calcium, or magnesium.
- Certain medications, like digoxin or anti-arrhythmics.
- Respiratory or metabolic disorders, such as chronic obstructive pulmonary disease (COPD) or diabetic ketoacidosis.
- Age-related changes or genetic predispositions.
