Which heart rhythm can be corrected with an implanted pacemaker if symptomatic?

The heart rhythm that can be corrected with an implanted pacemaker if symptomatic is sinus bradycardia (SB). Sinus bradycardia refers to a slower than normal heart rate, typically defined as a heart rate of less than 60 beats per minute. This condition can lead to inadequate blood flow, resulting in symptoms such as dizziness, fatigue, or fainting.

In cases where sinus bradycardia causes significant symptoms or complications, an implanted pacemaker can be deployed to regulate the heart's electrical conduction system. The pacemaker sends electrical impulses to the heart, helping to maintain a heart rate that is adequate to meet the body’s needs, thus alleviating the symptoms associated with the bradycardia.

Other rhythms mentioned, such as normal sinus rhythm (NSR), sinus tachycardia (ST), and sinus arrhythmia (SA), typically do not require intervention with a pacemaker unless they are associated with significant underlying issues or symptoms that warrant such treatment. Normal sinus rhythm is the ideal, healthy rhythm; sinus tachycardia indicates a faster heart rate which, while potentially symptomatic, may not require pacemaker support unless severely problematic. Sinus arrhythmia is generally a normal variation in heart rate associated with breathing
