What is one potential cardiovascular side effect of Lithium?

Lithium is a mood stabilizer commonly used in the treatment of bipolar disorder, and it can have several effects on the cardiovascular system. Bradycardia, which refers to a slower than normal heart rate, is one notable side effect associated with the use of Lithium. This occurs because Lithium can alter the electrical conduction in the heart, influencing the heart rate.

In patients taking Lithium, changes in electrolyte levels and other physiological effects can lead to a decreased heart rate, which may not only cause symptoms like fatigue and dizziness but can also pose a risk especially in those with pre-existing heart conditions. Monitoring heart rate is important for individuals on Lithium, particularly because bradycardia can lead to more serious complications if not addressed.

In contrast, other options like hypotension, tachycardia, and arrhythmia can also occur with Lithium use or in related contexts but are less commonly cited specific side effects when it comes to Lithium. Bradycardia stands out in this context as it is a recognized cardiovascular effect directly linked to this medication.
