Which heart structure receives blood from the coronary sinus?Which heart structure(s) separates the right and left ventricles?The pacemaker of the heart is the _____.What does the right coronary artery arise fro
Supraventricular tachycardia with a constant cycle length of 365 milliseconds was induced by burst pacing from coronary sinus under isoproterenol infusion. The tachycardia became irregular and remained sustained although a spontaneous termination is observed in Figure 1. What is the mechanism of this ...
What is the function of the pinna? (a) Define parietal cells. (b) What is its function? What is the function of the coronary sinus? What is the function of the Nasopharynx? What is the functional importance of the fibrous skeleton of the heart?
Children’s Hospital. The laboratory used a3D printed model from CT scansof a teenage patient with an anomalous origin of the left coronary artery from the right sinus of Valsalva with the intramural, intraarterial course. Simpleware software and a Stratasys printer were used to prepare the model...
The right and left coronary arteries, branches of the ascending aorta, supply blood to the walls of the myocardium. After blood passes through the capillaries in the myocardium, it enters a system of cardiac (coronary) veins. Most of the cardiac veins drain into the coronary sinus, which open...
What should my heart rate be? As per the American Heart Association (AHA), if you are an adult, your heart rate should be in the range of 60 to 100 beats per minute. And if your age is between 6 and 15 years, your heart rate should be anywhere between 70 and 100 per minute. ...

There has been ongoing controversy as to whether aspirin should be used in patients with chronic heart failure (CHF). The argument for aspirin is that many patients have underlying coronary disease, and aspirin prevents reinfarction and other vascular events. Arguments against the routine use of ...
Protocatechuic acid and protocatechuic aldehyde were mixed with 10mg/kg each, and the effect of increasing coronary sinus flow was weaker than that of protocatechuic acid alone, and the time was shorter. However, it is superior to protocatechuic aldehyde alone in reducing arterial and venous oxygen...
The right atrium also receives blood from the walls of the heart through the coronary sinus, whose opening of the post caval vein is guarded by the value of inferior vena cavae or Eustachian valve. It directs the blood to the left atrium through the foramen ovale, in the fetal stage, ...
