May be normal in athletes.Sinus Tachycardia The conduction pathway is the same as that in sinus rhythm. The discharge rate from the sinus node increases because of vagal inhibition or sympathetic stimulation. the sinus rate is 101-200 BPM.

Atrial Flutter An atrial tachydysrhythmia identified by recurring, regular, sawtooth-shaped flutter waves that originate from a single ectopic focus in the right atrium, less commonly, can occur in left atrium.Atrial Fibrillation Characterized by a total disorganization of atrial electrical activity due to multiple ectopic foci resulting in loss of effective atrial contraction.May be paroxysmal or persistant (+7 days). Most common dysrhythmia.Premature Ventricular Contractions (PVCs) A contraction originating in an ectopic focus in the ventricles. It is the premature occurence of a QRS complex, which is wide and distorted in shape compared with a QRS complex originated from the normal conduction pathway.Multifocal PVCs Unifocal PVCs Ventricular Bigeminy When every other beat is a PVC

Ventricular Trigeminy When every third beat is a PVC Couplet Two consecutive PVCs Ventricular Tachycardia A run of 3 or more PVCs. It occurs when an ectopic focus or foci fire repetively and the ventricle takes control as the pacemaker.Monomorphic Ventricular Tachycardia QRS complexes that are the same shape, size, and direction.Polymorphic Ventricular Tachycardia believed to be tornadoes de pointes ribbon like Occurs when the QRS complexes gradually change back and forth from one shape, size, and direction to another over a series of beats.Ventricular Fibrillation A severe derangement of the heart rhythm characterized on ECG by irregular waveforms of varying shapes and amplitude. This represents firing of multiple ectopic foci in the ventricle. Ventricle is just 'quivering'

Premature Atrial Contraction A contraction originating from an ectopic focus in the atrium, in a location other than the SA node.Paroxysmal Supraventricular Tachycardia (PSVT) A dysrhythmia originating in an ectopic focus anywhere above the bifurcation of the bundle of His. P wave is often hidden in preceding T wave, but if seen may have an abnormal shape. The PR interval may be shortened or normal, and QRS is usually normal. Terms (17) Hide definitions
