Resting ECG

A most common resting ECG records the heart's electrical activity while the patient rests. Electrodes are placed on the chest, arms, and legs; the test takes only a few minutes.

It helps identify arrhythmias, heart attacks, and other irregularities in heart rhythm. While quick and painless, this test may not capture irregularities that occur only during physical activity or prolonged periods, making it suitable for routine checkups or initial assessments.

Stress ECG (Exercise ECG)

The stress ECG, also known as an exercise ECG, is performed while the patient is physically active, usually on a treadmill or stationary bike. This test evaluates how the heart performs under stress, which can reveal conditions like coronary artery disease, heart attacks, or exercise-induced arrhythmias.

By monitoring heart rate, blood pressure, and ECG readings during physical exertion, doctors can observe how well the heart adapts to increased demand and identify any issues that may not be visible during a resting ECG.

Holter Monitor ECG

A Holter monitor ECG is a portable device that continuously records the heart's electrical activity over a 24 to 48-hour period. This test is ideal for detecting intermittently irregularities, such as arrhythmias, that may not be present during a brief resting ECG.

The patient wears the device throughout their daily activities, and the collected data is analyzed to provide a detailed picture of heart function. The Holter monitor is handy for patients with dizziness, palpitations, or unexplained fainting symptoms.

Event Monitor ECG

An event monitor ECG is similar to a Holter monitor but is worn longer, typically up to a few weeks. The patient activates this device when they experience symptoms like palpitations or dizziness. The monitor records the heart's activity during these events, which helps doctors identify and diagnose irregular heart rhythms.

It benefits patients with infrequent symptoms, allowing for targeted data collection only when symptoms occur and assisting doctors to make accurate diagnoses based on real-time information.

These waveforms provide crucial insights into heart conditions, helping healthcare providers diagnose potential issues early. Let’s dive into the different parts of an ECG test and what each one represents.

Understanding the ECG Wave Patterns

ECG results are represented by wave patterns showing the electrical impulses traveling through the heart. These waves include the P, QRS complex, and T waves, each corresponding to the heart’s electrical cycle stages. A typical ECG pattern reflects the healthy rhythm and coordination of the heart.

However, irregularities in these patterns can indicate potential issues such as arrhythmias, heart attacks, or other cardiovascular conditions. Correctly interpreting these waveforms is essential for accurate diagnosis and treatment.

P Wave

The P wave represents the electrical impulse that triggers the contraction of the atria, the heart’s upper chambers. A normal P wave indicates healthy atrial function. Abnormalities in the P wave, such as its size or shape, can signal atrial enlargement or issues with atrial rhythm.

If the P wave is absent or unusual, it may suggest atrial fibrillation or other rhythm disorders. Monitoring the P wave can help doctors identify potential problems early and initiate necessary treatments.

QRS Complex

The QRS complex reflects the electrical activity that causes the ventricles, the heart’s lower chambers, to contract. A typical QRS complex is narrow and sharp, signifying efficient electrical conduction through the heart.

If the QRS complex is vast or irregular, it may indicate problems with the ventricles' electrical conduction, such as a bundle branch block or heart attack. Doctors analyze the QRS complex to assess the heart’s ability to pump blood effectively and to detect any underlying issues.

T Wave

The T wave represents the period when the ventricles relax after contracting. A standard T wave is upright and smooth, reflecting healthy ventricular repolarization.

Abnormalities in the T wave, such as inverting or flattening, can indicate conditions like ischemia, electrolyte imbalances, or a heart attack. The shape and size of the T wave provide vital clues about the recovery phase of the ventricles and can help doctors assess overall heart function.

Abnormal Readings Indications

Abnormal ECG readings can suggest various heart conditions, such as arrhythmias, heart attacks, or heart disease. For example, an irregular P wave may signal atrial fibrillation, while a prolonged QRS complex could indicate a blockage in the heart’s conduction system.

Changes in the T wave may point to ischemia or electrolyte disturbances. Any abnormal findings require further investigation and can lead to an accurate diagnosis, allowing for timely treatment to prevent serious complications and improve heart health.
