If voltage-gated k channels were impaired in cardiomyocytes, the T wave (ventricle repolarization) part of the ECG would be altered.
An electrocardiogram (ECG) is a quick test that can be used to examine the electrical activity and rhythm of your heart. The electrical signals that your heart beats out each time it beats are picked up by sensors that are affixed to your skin.
The P wave, which indicates depolarization of the atria, the QRS complex, which shows depolarization of the ventricles, and the T wave, which represents repolarization of the ventricles, are the three primary elements of an ECG.
If your pulse is hard to feel, too fast, or too irregular to count precisely, an ECG may be beneficial. An abnormally high heart rate (tachycardia) or an abnormally sluggish heart rate can both be found using an ECG (bradycardia). a heartbeat. An ECG can identify unsteady heartbeats (arrhythmias).
