de Winter syndrome is an electrocardiogram (ECG) pattern which often represents sudden near blockage of the left anterior descending artery (LAD). [1] [5] Symptoms include chest pain, shortness of breath, and sweating.
Ectopic atrial tachycardia (EAT), also known as automatic atrial tachycardia, is an arrhythmia caused by both atria with abnormally fast atrial rates. [12] The ectopic focus's firing rate is quicker than that of the sinus node, and it overrides normal sinus node activity. Heart rates in children and adolescents can range from 130 to 210 beats ...
Many modern ICDs use a combination of various methods to determine if a fast rhythm is normal, supraventricular tachycardia, ventricular tachycardia, or ventricular fibrillation. Rate discrimination evaluates the rate of the lower chambers of the heart (the ventricles ) and compares it to the rate in the upper chambers of the heart (the atria ).
Pressing down gently on the top of closed eyes may also bring heartbeat back to normal rhythm for some people with atrial or supraventricular tachycardia (SVT). [15] This is known as the oculocardiac reflex. [15] A 2023 review confirms the success of the Valsalva maneuver as a non-pharmaceutical intervention in PSVT. [16]
Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or other cardiac arrhythmia is converted to a normal rhythm using electricity or drugs. Synchronized electrical cardioversion uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle , restoring the activity of the ...
JET in a 2-month-old girl following cardiac surgery. In this case the right bundle branch block was present during tachycardia and during normal sinus rhythm. JET is most commonly diagnosed using a 12-lead ECG. The appearance is usually of a tachycardia with rapid, regular ventricular rates of 170-260 beats per minute. [6]

Wandering atrial pacemaker (WAP) is an atrial rhythm where the pacemaking activity of the heart originates from different locations within the atria. [1] This is different from normal pacemaking activity, where the sinoatrial node (SA node) is responsible for each heartbeat and keeps a steady rate and rhythm. Causes of wandering atrial ...
