- Sick Sinus Syndrome is a malfunction
of the sinoatrial node causing any combination of bradycardic dysrhythmias, sinus arrests, and tachycardic dysrhythmias.
- Symptoms include dyspnea on exertion, palpitations, fatigue, and/or chest pain.
- On a cardiac monitor, patients can be bradycardic and immediately after tachycardic as a common presentation of the dysrhythmias.
- Chronotropic incontinence is often a symptom of SSS and is defined as the inability for the heart to increase its rate with increased demand.
- Patients will usually end up with a permanent pacemaker upon diagnosis of SSS.
