The following arrhyhmias arise in the atrium. Dependent on the amount of conduction block in the AV-node the ventricles follow the atrial contraction. However, at higher atrial rates the AV-node starts to block conduction from atrium to ventricle. | |||

A sinus tachycardia usually has a gradual start and ending. Diagnosis on the ECG can be made by the morphology of the P-wave. The P-wave has the same morphology during sinus tachycardia as during normal sinus rhythm. | A sinus tachycardia usually has a gradual start and ending.

====Management:==== | |||
No treatment is indicated, usually the sinustachycardia will pass when the external trigger is removed. If patients have complaints a beta-blocker can be administered. | |||
