A 36-Year-Old Woman with Coronary Artery Dissection Two Weeks after Abortion.

Spontaneous coronary artery dissection is a rare cause of acute coronary syndrome and sudden cardiac death. We report coronary artery dissection in a 36-year-old woman with retrosternal chest pain 2 weeks after abortion. Electrocardiography showed ST elevation in leads V2-V4 and ST depression in the inferior leads.

Significance of a fragmented QRS complex in patients with chronic total occlusion of coronary artery without prior myocardial infarction.

Objective: Fragmented QRS (fQRS) complexes that have numerous RSR´ patterns represent alteration of ventricular depolarization. We evaluated the relationship between fQRS and poor coronary collateral circulation and the diagnostic ability of fQRS for myocardial scar detection in patients with chronic total occlusion (CTO) without a history of myocardial infarction.

Methods: The study population consisted of patients undergoing coronary angiography with a suspicion of CAD.

The role of the fragmented QRS complexes on a routine 12-lead ECG in predicting non-responsiveness to cardiac resynchronization therapy.

Objective: Cardiac resynchronization therapy (CRT) is introduced as a promising therapeutic option in heart failure (HF) patients with ventricular dyssynchrony.The challenge, however, is identifying the patients who are suitable candidates for this procedure. Fragmented QRS (fQRS) is associated with subendocardial fibrosis and myocardial scars.
