چکیده
The lady has a 12 18-month history of a progressive exertional dyspnea with chest tightness. Her heart rate was 68 per minute and blood pressure was 110/85 mmHg with no significant postural changes. The jugular venous pressure was normal at 2 cm above sternal angle and her carotid pulses were of low volume and delayed upstroke. The first heart sound (S1) was normal, however, S2 was soft and single and there was S4 gallop. A grade 3/6 harsh, late-peaking ejection systolic murmur was heard along the left sternal border with some radiation to carotid arteries. Answers and explanations

Background Sudden cardiac death is an important problem, because the patients have no opportunity to receive medical service. Recently some electrocardiogram (ECG) parameters are used for predicting arrhythmias, including P wave duration for predicting atrial arrhythmias and corrected QT and T wave peak to end interval (Tp-e), for predicting ventricular arrhythmi...
متن کاملThe Effect of Administering Equine Chorionic Gonadotropins (eCG) on Reproductive Performance of Dairy Cows with a CO-Synch + CIDR Protocol and Insemination at a Fixed Time
The success of a fixed-time artificial insemination (FTAI) program depends on a high ovulation rate during a short interval. Equine chorionic gonadotropin (eCG) has been used in FTAI protocols to improve follicular growth and thereby to produce larger, more responsive follicles for ovulation with increased pregnancy rates. The aim of the present study was to evaluate the effects of eCG on concept...

Background & Aims: The most common diagnostic modality for pulmonary emboli is CT angiography (CTA). Because of the availability and inexpensiveness, taking an electrocardiogram (ECG) is the first step in patients suspicious to pulmonary emboli. However, ECG does not provide any sensitive or specific manifestations for diagnosis of pulmonary emboli. We aim to evaluate the correlation between...
