Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation , an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding ...
Heart disease is the leading cause of death for men and women in the U.S., which should make heart health a focus for the majority of the population. But despite how serious — and deadly ...
The ganglionated plexi (autonomic ganglia of the heart atrium and ventricles) can also be a source of atrial fibrillation, and is sometimes also ablated for that reason. [16] Not only the pulmonary vein, but the left atrial appendage can be a source of atrial fibrillation and is also ablated for that reason. [17]
The fourth heart sound or S 4 is an extra heart sound that occurs during late diastole, immediately before the normal two "lub-dub" heart sounds (S 1 and S 2).It occurs just after atrial contraction and immediately before the systolic S 1 and is caused by the atria contracting forcefully in an effort to overcome an abnormally stiff or hypertrophic ventricle.
It’s possible you could have a heart rhythm disorder like atrial fibrillation, or Afib. “When we're trying to evaluate palpitations, we want to identify whether there's an actual arrhythmia ...
Anticoagulants: To prevent embolization. Beta blockers: To block the effects of certain hormones on the heart to slow the heart rate. Calcium Channel Blockers: Help slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles).
