As a medical professional with expertise in cardiology, I can tell you that an electrocardiogram (ECG or EKG) is a non-invasive test that detects and records the electrical activity of the heart. This test is crucial for diagnosing various heart conditions. Here's what can typically be detected by an ECG:
1. Heart rate: The number of heartbeats per minute.
2. Heart rhythm: The pattern of the heartbeats, which can indicate conditions like arrhythmias.
3. Heart attack: ECG can show changes in the electrical activity that occur during a heart attack.
4. Myocardial infarction (MI): Also known as a heart attack, it can be detected by the ECG as damage to the heart muscle.
5. Ischemia: A lack of blood flow to the heart, often due to coronary artery disease.
6. Cardiomyopathy: A disease of the heart muscle that can be detected by changes in the ECG waveforms.
7.
Long QT syndrome: A heart rhythm condition that can lead to a dangerous abnormal heart rhythm.
8.
Wolff-Parkinson-White (WPW) syndrome: A pre-excitation syndrome that can be identified by an ECG.
9.
Ventricular hypertrophy: An increase in the size of the heart's ventricles, which can be inferred from the ECG.
10.
Atrial hypertrophy: An increase in the size of the heart's atria, which can also be detected by an ECG.

1. Pericarditis: Inflammation of the pericardium, the sac-like membrane surrounding the heart, which can cause changes in the ECG.

2. Electrolyte imbalances: Certain imbalances, like those of potassium or calcium, can affect the ECG readings.
It's important to note that while an ECG is a powerful diagnostic tool, it is not always definitive and may need to be combined with other tests for a complete diagnosis.

An ECG (electrocardiogram) records the electrical activity of your heart at rest. It provides information about your heart rate and rhythm, and shows if there is enlargement of the heart due to high blood pressure (hypertension) or evidence of a previous heart attack (myocardial infarction).
