Frequently Asked Questions

How does anesthesia affect the cardiovascular system?

The overall function of the cardiovascular system is also indicated by the blood pressure and oxygen level on the monitor. Different types of anesthesia affect the heart in different ways. As a board-certified anesthesiologist, I see these effects each and every day on healthy and sick hearts.

What is a normal heart rate under general anesthesia?

It is not uncommon for adults under general anesthesia to have a heart rate between 40 and 60 bpm, and may vary secondary to home medications (ie: Beta blockers). Therefore it must be established whether the current heart rate is inadequate for the clinical situation.

Can general anesthesia cause heart beats to become irregular?

General anesthesia can cause heart beats to become irregular, notes the University of Maryland Medical Center. Irregular heart beats are also known as arrhythmia. This condition is usually occurs because the flow of blood is insufficient to meet the body’s needs, causing the heart rate to become irregular as the heart adjusts to compensate.

Can anesthesia affect a cat's heart rate?

Anesthesia and other factors, such as surgery itself, can affect heart rate. By monitoring your pet’s heart rate, your veterinarian can make anesthetic adjustments quickly. An electrocardiogram (ECG) monitors your cat’s heart rate and heartbeat pattern. It can detect abnormal heartbeats called arrhythmias.
