How to identify hidden signs of dangerously slow heart rates

The heart remains a complex organ, and any sudden fluctuations can indicate that something is not right. According to Dr Nityanand Tripathi, principal director and HOD of cardiology and electrophysiology at Fortis Hospital, Delhi, a heart rate consistently falling below 60 beats per minute may require serious attention.

This condition, known as bradycardia, can be normal for athletes or during sleep, but a persistently slow pulse should not be brushed aside.

The cardiologist explained that the heart’s rhythm is controlled by the sinoatrial (SA) node, the body’s natural pacemaker.

"When this electrical system weakens, degenerates, or malfunctions, the heart may fail to pump adequate oxygen-rich blood to vital organs," Dr Tripathi noted on Thursday. This reduced circulation can eventually affect brain function and physical stamina.

Signs you should not ignore

The expert warned that bradycardia often remains undetected because signs are "mistakenly attributed to stress, fatigue, or the natural process of ageing." Patients must monitor for the following symptoms:

• Persistent fatigue
• Unexplained weakness
• Dizziness
• Light heartedness
• Signs which are a bit more "concerning" include:
• Confusion
• Shortness of breath during routine activities
• Chest discomfort
• Fainting/near-fainting episodes

Diagnosis

Older adults over 65 are particularly vulnerable due to age-related wear. For diagnosis, Dr Tripathi recommended an electrocardiogram (ECG) or a Holter device.

He stated, "Management depends on the underlying cause and severity and may range from adjusting medications to correcting metabolic imbalances." For many, pacemaker therapy remains the most effective solution.
