We have recently reported in canine Purkinje fibers that acetylcholine (ACh) can reverse the positive voltage shift of the pacemaker current ( i f ) induced by β -adrenergic stimulation while having no direct action of its own [3]. We have now investigated this effect of ACh on the cyclic...
What would be the effect on the heart rate if an ectopic pacemaker took over for the SA node? Pacemaker cells Pacemaker cells are one of the types of cardiac cells apart from the muscle cells. It is associated with the conduction system o...
Chances are you might have at least two lithium-ion batteries on your body right now – one on your wrist, and one in the phone in your pocket. You may have multiple more if you’re holding a car key fob or have a pacemaker or any other electronic device
So when you're talking about a heart pacemaker as a prosthetic, you're talking about something that isn't just, "I'm missing my leg," it's, "if I don't have this, I can die." And at that point, a prosthetic becomes a symbiotic relationship with the human body. And four of th...
A negative native X-ray does not exclude spondylodiscitis. For patients with contraindications to MRI (devices like a pacemaker and ventriculoperitoneal shunt) or with claustrophobia, Computed Tomography (CT) is the best alternative. The enhanced CT studies provide information on endplate erosion, ...
• If you feel your pacemaker is infected. Signs of infection are same as the signs of inflammation: redness, pain, and warmth. A pacemaker is a device which is installed under your skin to regulate your heart beat. • A severe headache that appears suddenly ...
If you have blockages in heart arteries( Coronary artery disease ) it might cause the area in your heart to not get enough blood. Angioplasty is a procedure used to open blocked coronary arteries to avoid a heart atack or pain. This can be done with ballon or Stent Placement Pacemaker Imp...

Do you think ventricular fibrillation is more or less serious than atrial fibrillation in a human? Explain your reasoning. Which is the normal pacemaker of the heart? A) AV junction B) SA node C) AV node D) ventricle The term fibrillation refers to an irregular,...
Explain the term 'pacemaker of the heart.' Which event occurs first during diastole? A) Blood flows into the relaxed atria while the ventricles contract. B) The atria and ventricles are relaxed, and blood flows into the atria. C) The atria and ventricles contract simult...
