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. An inappropriate sinus tachycardia is diagnosed by when the sinus tachycardia is persistent (therefore non-paroxysmal) and no trigger can be identified. | A sinus tachycardia usually has a gradual start and ending.

No treatment is indicated, usually the sinustachycardia will pass when the external trigger is removed. If patients have persistent complaints, the trigger cannot be removed or in case of a inappropriate sinus tachycardia a beta-blocker can be administered. Patients with a contra-indication for beta-blockers can use nondihydropyridine calcium-channel blockers. | No treatment is indicated, usually the sinustachycardia will pass when the external trigger is removed.
