Myocardial Infarction
Myocardial infarction, commonly referred to as heart attack, is a condition characterized by necrosis of the heart muscles due to development of ischemia that stays on for prolonged periods. Such a condition develops when the heart does not receive oxygen and blood due to blockage in the coronary arteries.[…][symptoma.com]
Acute Myocardial Infarction
We herein report the case of a 25-year-old Japanese woman with left-main-trunk acute myocardial infarction (LMT-AMI). She had cardiogenic shock, so emergency percutaneous intervention was performed. Intravascular ultrasound of LMT-AMI showed that the three-layered structure of the intima, tunica media, and[…][ncbi.nlm.nih.gov]
Wolff-Parkinson-White Syndrome
Wolff-Parkinson-White (WPW) syndrome is defined as the presence of an accessory atrioventricular pathway which is manifested as delta waves and short PR interval on electrocardiography[ncbi.nlm.nih.gov]
Electrocardiography (ECG) of patients with WPW syndrome portrays a short PR interval and a wide QRS interval with a delta wave.[ncbi.nlm.nih.gov]
Elective cardioversion restored sinus rhythm, and the ECG showed a wide QRS complex, short PR interval, and delta wave, indicating the presence of an accessory pathway and[ncbi.nlm.nih.gov]
