Heart rate is defined as the number of QRS complexes that occur in 1 minute. QRS complexes measure ventricular activity in the heart known as ventricular depolarization. You can use whichever method works best for you if the patient has a regular rhythm. Warnings If the patient has an irregula...
Right ventricular overload, right heart failure, and death may result from these severe pathologies [7,8,9]. However, no effective treatment has been discovered. We established this disease model via a low oxygen (10%) treatment (hypoxia) and monocrotaline (MCT) injections to induce ...

Rate Control of Atrial Fibrillation: By How Much Should the Ventricular Rate be Lowered?Atrial Fibrillationg <3>Heart rate (HR) should be neither too high, since it can be responsible for tachycardia-induced cardiomyopathy [1, 2], nor too low, since it can facilitate the appearance of heart...

Slow heart rate (bradycardia):Your heart rate is modulated by thyroid hormone. In people with hypothyroidism, the heart rate is typically 10 to 20 beats per minute slower than normal, especially in patients who also have heart disease.
However, submucosal injection of epinephrine can potentially result in systemic effects such as severe hypertension, ventricular tachycardia, and intestinal ischemia. However, the rare reports of these complications result mainly from hemostatic procedures that used higher concentrations of epinephrine (1:1000...
Atherosclerosis refers to the build-up of plaque in the inner walls of arteries. This plaque consists of fat, cholesterol, calcium, and various proteins, and it can reduce/block blood flow through the arteries.Answer and Explanation: Atherosclerosis is closely related to blood cholesterol levels....
Mark out several consecutive R-R intervals on a piece of paper, then move them along the rhythm strip to check if the subsequent intervals are similar. Hint If you are suspicious ofatrioventricularblock(AV block), map out theatrialrateand theventricularrhythmseparately (i.e. mark the P waves...
Note that some operators may prefer to perform vasoreactivity testing first without the guidewire, allowing Ach challenge prior to any short-acting nitrate administration. HMR = hyperemia microvascular resistance; IC = intracardiac; LVEDP = left ventricular end-diastolic pressure; LV gram = left ...
