Syncope without prodrome is a significant risk factor for cardiac syncope and poor outcome. during which sinus bradycardia and arrhythmia are seen but not to a degree that produces symptoms. The indication for pacemaker placement with SSS is symptomatic bradycardia. second in duration.

Smith : "What was the outcome?" Other cardiac-related causes for syncope associated with acute MI may include malignant ventricular arrhythmias and bradyarrhythmias including AV block. Former Resident: "They took him but they rolled their eyes at me (Smith editorial comment: how often have they rolled their eyes at YOU?).

Atrial fibrillation is also a predictor of worse outcomes in this case (Alborzi). Other Arrhythmias ( PACs, PVCs, AFib, Bradycardia and AV conduction disorders — potentially lethal VT/VFib ). NOTE: Prediction of cardiac contusion "severity" on the basis of cardiac arrhythmias and ECG findings — is an imperfect science.

Reflex syncope is defined as a transient loss of consciousness due to a neurally mediated reflex causing sudden-onset vasodilation and bradycardia, leading to a steep decrease in blood pressure and cerebral hypoperfusion. Thus, once the aetiology is established, further diagnostic tests are seldom performed.

There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Torsades in acquired long QT is much more likely in bradycardia because the QT interval following a long pause is longer still. The patient stabilized and had a good outcome. There is atrial fibrillation.

There’s sinus bradycardia, first degree AV block, normal axis, delayed R wave progression, and normal voltages. Hyperacute T waves are deflating, suggesting reperfusion but there is still reciprocal change in I/aVL and ST depression in V2, and the bradycardia is worse. Below is the ECG. What do you think? Take home 1.

The patient's long term outcome is unknown. Although the QRS has narrowed and the sinus node has gone back to work, there is still subtle upsloping STD in the lateral precordial leads and subtle T wave peaking. Discussion: This is a case of an initial ECG showing very subtle signs of hyperkalemia.
