Sick sinus syndrome diagnosis
Some tests use to diagnosis for Sick sinus syndrome include:
2. determination of sinus node function: can be suspected in patients with the application of the method to choose.
Sick sinus syndrome is diagnosed by ECG characteristics as follow:
Sinus node dysfunction, including ECG itself and secondary to sinus node dysfunction and the escape beat or escape rhythm, but also complicated by the rapid burst arrhythmia and other parts of the conduction system involvement quietly ECG performance.
1. sinoatrial block and sinus static and marked sinus bradycardia;
2. escape, or continuous burst escape rhythm, escape capture bigeminy, wandering rhythm;
3. associated with atrial tachyarrhythmias, such as frequent atrial premature beat. paroxysmal burst or recurrent atrial fibrillation, atrial flutter or atrial tachycardia, sinus rhythm with the slow formation of the bradycardia-tachycardia syndrome. After the automatic cut-off tachyarrhythmias, regular sinus rhythm in up to more than two seconds after the interval;
4. pacing atrioventricular junction and (or) conduction dysfunction, performance appears to delay escape beat atrioventricular junction, the atrioventricular junction slow escape rhythm (cycle of escape> 1.5s), or atrioventricular block, occasionally combined bundle branch block.
