By: Presented by Ri

Sick sinus syndrome

* Multiple manifestations on EKG
* Sinus bradycardia
* Sinus arrest
* Sinoatrial block
* Bradycardia –tachycardia syndrom

Bradycardia-tachycardia syndrome

* Alternating patterns of bradycardia and tachycardia
* Often there is a long pause (asystole) between heartbeats, especially after an episode of tachycardia
* Tachycardia: PSVT, atrial fibrillation, atrial flutter

causes

* Most cases are idiopathic
* Intrinsic causes
* Extrinsic causes
* Cardiac surgery, especially to the atria, is a common cause of sick sinus syndrome in children.

Clinical manifestations

* Many people with sick sinus syndrome have no symptoms
* Symptoms are related to the decresed cardiac output that occurs with the bradyarrythmias or tachyarrythmias
* Fainting , Fatigue , Shortness of breath, or dyspnea, Chest pains , Confusion , Palpitations
* Bradycardia-tachycardia syndrome: peripheral thromboembolism and stroke

Treatment

* If the disorder is asymptomatic (without symptoms), no treatment is necessary
* Bradycardia-tachycardia syndrome
* Associated tachycardia may be treated with medications after the person is protected from symptomatic bradycardia by a pacemaker.
* Warfarin has been shown to decrease the number of strokes and embolic events
