In normal sinus rhythm, what does the P-wave, the PR interval, QRS complex, and QT interval reflect?ECG:An ECG, or electrocardiogram, is an electrical readout of the heart which measures the electrical output of all heart chambers during cardiac cycles. Th...
of Rhythm Management (AFFIRM) trial (1), the largest randomized trial of management strategies for atrial fibrillation, seemed to resolve a major issue: Rate control and the use of anticoagulation are equivalent to restoring and maintaining normal sinus rhythm by using contemporary antiarrhythmic drugs...
When sick sinus bradycardia begins to be of significant impact to the patient’s life, a pacemaker is usually implanted to keep the heart beating in normal sinus rhythm. Pacemaker implantation has a high rate of success in treating sick sinus bradycardia, however, in very young children, the p...
There are also non-drug treatment options for atrial fibrillation. The most commonly used is electrical cardioversion. This is a procedure that attempts to convert the abnormal rhythm to a normal one with a controlled electrical current passed through the heart. ...
Sinus rate was increased in rabbits dying suddenly, but was decreased in survivors. This also was true in isolated preparations. Microelectrode recordings from ventricular trabeculae both from patients with end-stage failure and from failing rabbits showed that in half of the preparations, delayed ...
Certain medications can reset your heart rate readings and give you a new normal. "Beta blockers and calcium channel blockers are the main ones that can lower a heart rate," says Taub. Both relax your heart, which can slow it down. That's not necessarily dangerous, but check with your...
and chronic preganglionic autonomic insufficiency. If you have one of these disorders, you are likely to have other symptoms, such aserectile dysfunction(inability to have or maintain an erection), loss of bladder and bowel control, loss of the normal reflexes of your pupils, or decreased sweat...
