A prolonged PR interval (>0.20 seconds) is indicative of delayed conduction between the atria and ventricles.
Ventricular fibrillation is a chaotic and ineffective rhythm that prevents proper blood circulation and can lead to sudden cardiac arrest.
Sinus bradycardia, a slower-than-normal heart rate, is often benign and can occur during sleep or in athletes.
VT is a fast, regular rhythm that can compromise cardiac output and lead to ventricular fibrillation if untreated.
Atrial fibrillation (AFib) is the most common arrhythmia, characterized by irregular and often rapid heart rhythm.
