It is a type of supraventricular tachycardia (SVT), meaning that it originates from a location within the heart above the bundle of His. AV nodal reentrant tachycardia is the most common regular supraventricular tachycardia. It is more common in women than men (approximately 75% of cases occur in females). The main symptom is palpitations.
Supraventricular tachycardia (SVT) is an umbrella term for fast heart rhythms arising from the upper part of the heart. [2] This is in contrast to the other group of fast heart rhythms – ventricular tachycardia , which start within the lower chambers of the heart . [ 2 ]
Arrhythmia may be classified by rate (tachycardia, bradycardia), mechanism (automaticity, re-entry, triggered) or duration (isolated premature beats; couplets; runs, that is 3 or more beats; non-sustained = less than 30 seconds or sustained = over 30 seconds). [citation needed] Arrhythmias are also classified by site of origin: [citation needed]
The cause of the palpitations during these conditions is often a sustained supraventricular tachycardia or ventricular tachyarrhythmia. [1] Supraventricular tachycardias can also be induced at the termination of exercise when the withdrawal of catecholamines is coupled with a surge in the vagal tone . [ 1 ]
Finger heart is a hand gesture in which the subject has a palm up fist, raises their index finger and brings their thumb over it so as to form a small heart shape. It signals a similar gesture to that of the two-handed heart. It originates from South Korean culture and was used by athletes during the Pyeongchang 2018 Olympic Games. [18]
Defibrillation is a treatment for life-threatening cardiac arrhythmias, specifically ventricular fibrillation (V-Fib) and non-perfusing ventricular tachycardia (V-Tach). [1] [2] A defibrillator delivers a dose of electric current (often called a counter-shock) to the heart.

Over 99% of individuals in the general population will have at least one PAC in a 24 hour period. [6] Many PACs can indicate increased risk of atrial fibrillation and/or ischemic stroke . [ 6 ] The threshold for number of PACs which substantially raises the risk atrial fibrillation is debatable, but some estimates range between in excess of 500 ...
