Bradycardia :
Any heart rate that is less than 60 beats per minute is called bradycardia. In a normal language, it is called a slow heart rate. Bradycardia can be mostly seen over the age of 70. Some of the causes include electrolyte imbalance, certain medications like beta blockers, and hypothyroidism, or it may also be even due to an underlying cardiac disease such as rheumatic heart disease or sick sinus syndrome, which needs to be evaluated. Athletes are more prone to have a slow heart rate. Patients with bradycardia may present with symptoms like unexplained fatigue, palpitations, chest pain, dizziness, syncope, and needs that need to be evaluated and treated. Most of the patients remain asymptomatic. Some of the investigations that might be suggested by a cardiologist to rule out the cause of bradycardia may include ECG, 24-hour holter monitoring, and exercise tests. Treatment of bradycardia includes implantation of a temporary pacemaker or a permanent pacemaker if required. The underlying cause for bradycardia needs to be ruled out and treated if necessary.
