P wave Atrial depolarization
QRS wave Ventricular depolarization
T wave Ventricular repolarization
Normal sinus rhythm the characteristic rhythm of the healthy human heart.
Sinus arrhythmia a normal physiological phenomenon, most commonly seen in young, healthy people.
Sinus bradycardia a sinus rhythm with a rate that is lower than normal. Below 60 bpm
Sinus tachycardia a sinus rhythm with an elevated rate of impulses, defined as a rate greater than 100 beats/min (bpm) in an average adult.
Premature atrial contractions PAC a common cardiac dysrhythmia characterized by premature heartbeats originating in the atria.
Supraventricular tachycardia A regular, narrow complex tachycardia with a rate of 150-250 bpm.
Atrial fibrillation is a quivering or irregular heartbeat (arrhythmia) that can lead to blood clots, stroke, heart failure and other heart-related complications
Atrial flutter A chaotic circular conduction path creates a saw tooth baseline of flutter waves.
Junctional rhythms occurs when the electrical activation of the heart originates near or within the atrioventricular node, rather than from the sinoatrial node. Because the normal ventricular conduction system (His-Purkinje) is used, the QRS complex is frequently narrow.
Premature ventricular contractions PVCs An ectopic focus in the ventricles fires prematurely before the normal impulse through the SA node and atria.
Ventricular tachycardia There is a wide, blunt, rapid waveform with no discernible P or T wave.
Ventricular fibrillation a rapid, life-threatening heart rhythm starting in the bottom chambers of the heart. It can be triggered by a heart attack.
Asystole A flatline is the state of total cessation of electrical activity from the heart, which means no tissue contraction from the heart muscle and therefore no blood flow to the rest of the body.
Pulseless electrical activity PEA There is a normal appearing tracing such as sinus bradycardia but the patient has no pulse.
