Are beta-blockers contraindicated in bradycardia?

Patients who have either acute or chronic bradycardia and/or hypotension have relatively contraindication to beta-blocker usage.

Can I take beta-blockers with bradycardia?

You shouldn’t take beta-blockers if you have low blood pressure or a slow pulse, because bringing down your heart rate more can cause dizziness and lightheadedness.

Why do beta blockers cause bradycardia?

Beta-blockers cause bradycardia by antagonizing the actions of catecholamines produced by the sympathetic nerves at the cell receptor. Five of our patients were on the beta-blockers metoprolol or carvedilol.

Should I take metoprolol if I have bradycardia?

People with diabetes: Metoprolol can block the signs of low blood sugar, like increased heart rate, sweating, and tremors. People with a slow heart rate (bradycardia) or low blood pressure (hypotension): Metoprolol lowers blood pressure and heart rate.

What heart rate is too low to take metoprolol?

A heart rate of 55-60 is not unusual in people taking metoprolol. However, if a person had a heart rate that slow without a beta blocker, a doctor would be concerned that they would eventually develop symptoms from that slow of a heart rate.

Can beta blockers slow heart rate too much?

Beta blockers, also called beta adrenergic blocking agents, block the release of the stress hormones adrenaline and noradrenaline in certain parts of the body. This results in a slowing of the heart rate and reduces the force at which blood is pumped around your body.

How do beta blockers affect heart rate?

Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. Beta blockers cause the heart to beat more slowly and with less force, which lowers blood pressure. Beta blockers also help widen veins and arteries to improve blood flow.
