Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). While bradycardia can result from various pathologic...

Sinus bradycardia is a sinus rhythm with a reduced rate of electrical discharge from the sinoatrial node, resulting in a bradycardia, a heart rate that...

Reflex bradycardia is a bradycardia (decrease in heart rate) in response to the baroreceptor reflex, one of the body's homeostatic mechanisms for preventing...

Ictal bradycardia is when people with temporal lobe epilepsy experience bradycardia with their seizures (epileptic discharges). Bradycardia is defined...

pressure, but bradycardia reduces the overall cardiac output, particularly due to the diving reflex in breath-hold diving. Bradycardia is the response...

heart rate that is too slow – below 60 beats per minute – is called bradycardia. Some types of arrhythmias have no symptoms. Symptoms, when present,...

rhythms (if a bradycardia) can cause decreased cardiac output. Therefore, the person may exhibit signs and symptoms similar to other bradycardia such as lightheadedness...

An idioventricular rhythm is a cardiac rhythm characterized by a rate of <50 beats per minute (bpm), absence of P waves and widening of the QRS complex...

depolarization from the AV node back towards the SA node. Junctional bradycardia is a rhythm that still originates in the AV node or bundle of His, but...
