The meaning and interpretation of dynamic electrocardiogram

An electrocardiogram (ECG) is a commonly used heart examination tool that assesses heart health by recording changes in the heart's electrical activity. In a Holter, a monitoring device records the electrical activity of the heart over a period of time and converts it into numbers. This article will detail what the numbers on the ECG represent.

1. Heart Rate

The most basic number on an EKG is heart rate, which represents the number of times your heart beats per minute. Heart rate is very important to assess the normal function of the heart. A normal adult heart rate is usually between 60 and 100 beats per minute. A high heart rate may indicate an overloaded heart, heart disease, or excessive physical activity; a low heart rate may indicate abnormal heart function or a person with high exercise tolerance.

2. Cardiac Rhythm

In addition to heart rate, an EKG also records the heart's rhythm in numbers. A normal heart rhythm should be a regular, regular heartbeat. Any irregular heart rhythm can be a sign of a heart problem, such as arrhythmia, atrial fibrillation, etc. Abnormal heart rhythms may require further diagnosis and treatment.

3. Cardiac Waveforms

In a Holter, the electrical activity of the heart is broken down into different waveforms, including P waves, QRS complexes, and T waves. These waveforms represent the different stages of the heart during a heartbeat cycle. By examining the shape and characteristics of these waveforms, doctors can assess whether the heart's function and structure are normal, and determine whether there is heart disease or heart damage.

To sum up, the numbers on the Holter include heart rate, heart rhythm, and the shape of the heart's electrical activity. By analyzing these numbers, doctors can understand the health of the heart, diagnose and treat heart diseases. If you have an EKG, talk to your doctor about your specific situation.
