What is the impact of hypoxia on cardiac monitoring?

Hypoxia can lead to significant changes in heart rhythm and increase the risk of arrhythmias. When the body is deprived of adequate oxygen, the heart muscle may become ischemic, which can disrupt the normal electrical activity. This disruption can manifest as various arrhythmias, such as atrial fibrillation or ventricular tachycardia, depending on the severity and duration of the hypoxic event.

The heart relies on a constant supply of oxygen to sustain its electrical conduction system and maintain a regular rhythmic pattern. Therefore, when oxygen levels drop, it can impair the heart's ability to function effectively, leading to unstable rhythms. Monitoring for these changes is crucial in patients who are experiencing hypoxia, as early detection can facilitate timely intervention to prevent potential cardiac complications.
