ECG Test Overview
An electrocardiogram (ECG) test is a non-invasive procedure that records the electrical activity of the heart. It provides valuable insights into the heart’s rhythm, rate, and electrical conduction system. ECG tests are essential for diagnosing and monitoring various heart conditions.
There are several types of ECG tests, each with specific applications. A resting ECG is the most common type and is performed while the patient is at rest. An exercise ECG (stress test) is used to evaluate the heart’s response to exercise.
A Holter monitor is a portable ECG device that records the heart’s activity over 24 hours or more.
Electrical Conduction System of the Heart
The heart’s electrical conduction system is a network of specialized cells that coordinate the heart’s contractions. It consists of the sinoatrial (SA) node, the atrioventricular (AV) node, the bundle of His, and the Purkinje fibers.
- The SA node is located in the right atrium and is responsible for initiating the electrical impulse that triggers the heart’s contractions.
- The AV node is located between the atria and ventricles and delays the electrical impulse slightly, allowing the atria to fill with blood before the ventricles contract.
- The bundle of His divides the electrical impulse into left and right branches, which then travel down the ventricles.
- The Purkinje fibers are a network of fibers that distribute the electrical impulse throughout the ventricles, ensuring that they contract in a coordinated manner.
Understanding the electrical conduction system of the heart is crucial for interpreting ECGs and diagnosing heart conditions.

ECG Test Interpretation
ECG interpretation involves analyzing the electrical signals recorded by an ECG test to assess the heart’s electrical activity and identify any abnormalities. Understanding the basic principles and recognizing different ECG waveforms is crucial for accurate interpretation.
The ECG waveform consists of distinct components: P wave, QRS complex, and T wave. The P wave represents atrial depolarization, the QRS complex ventricular depolarization, and the T wave ventricular repolarization.
Waveform Analysis
The shape, duration, and amplitude of each waveform provide valuable information about the heart’s electrical activity:
- P wave:Normal duration is 0.08-0.12 seconds. Prolonged P waves may indicate atrial enlargement or conduction delay.
- QRS complex:Normal duration is 0.06-0.10 seconds. Wide QRS complexes may indicate ventricular hypertrophy or conduction abnormalities.
- T wave:Normal amplitude is less than 5mm. Inverted T waves may indicate ischemia or electrolyte imbalances.
Common Abnormalities
ECG abnormalities can indicate various heart conditions:
- Arrhythmias:Irregular heartbeats, such as atrial fibrillation or ventricular tachycardia.
- Ischemia:Reduced blood flow to the heart, causing ST-segment depression or T-wave inversion.
- Myocardial infarction:Heart attack, characterized by Q waves and ST-segment elevation.
- Conduction abnormalities:Delays or blocks in electrical conduction, such as bundle branch block or AV block.
Accurate ECG interpretation requires a thorough understanding of waveform characteristics and their clinical significance. By analyzing the ECG, healthcare professionals can identify potential heart conditions and make informed decisions about further diagnosis and treatment.
ECG Test Answers
Interpreting an electrocardiogram (ECG) requires a systematic approach and a thorough understanding of the electrical activity of the heart. By carefully analyzing the various waveforms, intervals, and segments, clinicians can identify potential abnormalities and make accurate diagnoses.
ECG Test Findings and Interpretations
The following table summarizes common ECG test findings and their corresponding interpretations:

| Bradycardia | Heart rate less than 60 bpm |
| Tachycardia | Heart rate greater than 100 bpm |
| Atrial Fibrillation | Irregular, disorganized P waves; irregular R-R intervals |
| Atrial Flutter | Regular, sawtooth-shaped P waves; rapid ventricular response |
| Premature Atrial Contractions (PACs) | Early, ectopic P waves; compensatory pause |
| Premature Ventricular Contractions (PVCs) | Wide, bizarre QRS complexes; may occur singly or in runs |
