Many of these rhythms are asymptomatic and do not require therapeutic measures. Different rhythms are the result supraventricular (atrial usually) foci.

Many of these rhythms are asymptomatic and do not require therapeutic measures. Different rhythms are the result supraventricular (atrial usually) foci. Ectopic supraventricular rhythms include supraventricular premature atrial tachycardia multifocal atrial tachycardia junctional Nichtparoxysmale Wandering atrial pacemaker supraventricular premature supraventricular premature beats (PAC) or premature supraventricular contractions (PAC, premature atrial contractions) are episodic pulses that are found in many people. They can occur with or without precipitating factors, such as coffee, tea, alcohol or Pseudoephidrin or it can be a sign of a cardiopulmonary disease even with normal heart function. They are common in patients with COPD. Occasionally they cause palpitations. The diagnosis results from the ECG (supraventricular extrasystole (PAC).). Supraventricular extrasystole (PAC). Lead II the T-wave is deformed by a PAC in accordance with the second stroke from the sinus node. Since the PAC occurs relatively early during sinus cycle, the sinus node rhythm reset and a break-less than fully compensatory-precedes the next sinus beat. PACs can normally abberant or not be transferred and are usually followed by a non-compensatory pause. PACs that are aberrant line (usually with the morphology of right bundle branch block) led, must be distinguished from premature ventricular origin. Atrial premature beats arise due to ectopic atrial beats that may occur singly or multiply after long sinus pauses or sinus arrest. Replacement punches of a single focus can produce a continuous rhythm (so-called. Ectopic atrial rhythm). Here, the heart rate is usually lower, typically changes the morphology of the P wave and the PR interval is slightly shorter than that of a sinus rhythm. The atrial atrial tachycardia is a regular rhythm caused by the consistent, rapid atrial activation by a single atrial focus. The heart rate is usually between 150 to 200 beats / min. However, with a very high atrial rate, a node dysfunction or AV block of digitalis may be associated and this results in a slower ventricular rate. These include enhanced atrial automaticity and intra-atrial reentrant mechanism. The atrial tachycardia is the rarest form (5%) of supraventricular tachycardias, which usually occurs in patients with a structural heart disease. Among the other causes include atrial irritation (eg., By a pericarditis), drugs such as digitalis, alcohol and inhalation of toxic gases. The symptoms are similar to those of other Tachykardieformen. The diagnosis results from the ECG. The QRS complexes P-waves precede that differ morphologically from the P-waves of a normal sinus rhythm. However, you can in the previous T wave hiding his (True atrial tachycardia.) True atrial tachycardia. This tachycardia with narrow QRS complexes has its origin in an abnormal auto-focus or an intra-atrial reentrant mechanism. The QRS complexes P-waves precede. There is usually a long RP tachycardia (PR
