Use the tips of your first two fingers (not your thumb) and press lightly over the artery. Count your pulse for 15 seconds and multiply by 4 to find your beats per minute. Some drugs and ...
Rate control to a target heart rate of fewer than 110 beats per minute is recommended in most people. Lower heart rates may be recommended in those with left ventricular hypertrophy or reduced left ventricular function.
Blocking this channel reduces cardiac pacemaker activity, selectively slowing the heart rate and allowing more time for blood to flow to the myocardium. By inhibiting the I f channel, ivabradine reduces the heart rate and workload on the heart. This is relevant in the usage of the medication to treat angina as well as congestive heart failure.
Metoprolol, sold under the brand name Lopressor among others, is a medication used to treat high blood pressure, angina, and a number of conditions involving an abnormally fast heart rate. It is also used to prevent further heart problems after myocardial infarction and to prevent headaches in those with migraines . [4]
Diltiazem is indicated for: Stable angina (exercise-induced) – diltiazem increases coronary blood flow and decreases myocardial oxygen consumption, secondary to decreased peripheral resistance, heart rate, and contractility. [15] [16] Variant angina – it is effective owing to its direct effects on coronary dilation.
When labetalol is given in acute situations, it decreases the peripheral vascular resistance and systemic blood pressure while having little effect on the heart rate, cardiac output and stroke volume, despite its α 1-, β 1 - and β 2-adrenergic receptor blocking mechanism.
t. e. Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. [11] High blood pressure usually does not cause symptoms itself. [1] It is, however, a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral ...
A medical monitoring device displaying a normal human heart rate. Heart rate (or pulse rate) [1] is the frequency of the heartbeat measured by the number of contractions of the heart per minute ( beats per minute, or bpm). The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide.
Dopamine, sold under the brand name Intropin among others, is a medication most commonly used in the treatment of very low blood pressure, a slow heart rate that is causing symptoms, and, if epinephrine is not available, cardiac arrest. [3]
By abolishing this negative feedback phentolamine leads to even less regulated norepinephrine release, which results in a more drastic increase in heart rate. Uses. The primary application for phentolamine is for the control of hypertensive emergencies, most notably due to pheochromocytoma.
