How Irregular Heart Rhythms Are Diagnosed and Treated

Irregular heart rhythms, also known as arrhythmias, can affect how efficiently the heart pumps blood and may lead to symptoms that interfere with daily life. At The NY Center for the Prevention of Heart Disease in Manhattan, Dr. Bradley Radwaner evaluates patients with irregular heart rhythms and develops treatment plans focused on restoring stability and supporting long-term heart health. Understanding how these conditions are identified and managed can help patients take an active role in their care.

Understanding Irregular Heart Rhythms

The heart relies on a coordinated electrical system to maintain a steady rhythm. When that system is disrupted, the heartbeat may become too fast, too slow, or irregular. Some arrhythmias are temporary and harmless, while others can increase the risk of complications such as stroke or heart failure.

Patients may notice symptoms such as palpitations, dizziness, fatigue, or shortness of breath. In some cases, irregular rhythms are discovered during routine evaluations before noticeable symptoms develop.

How Arrhythmias Are Diagnosed

Accurate diagnosis is essential for determining the appropriate treatment approach. Dr. Radwaner begins with a detailed review of symptoms, medical history, and any underlying conditions that may contribute to rhythm disturbances.

Diagnostic testing often includes electrocardiograms to evaluate the heart’s electrical activity and identify abnormal patterns. Because some arrhythmias occur intermittently, extended monitoring may be recommended using wearable devices that record heart rhythm over several days or weeks. Imaging studies and laboratory tests can also help assess heart structure and identify contributing factors.

By combining clinical findings with diagnostic data, a clearer picture of the arrhythmia can be established.

Treatment Options for Irregular Heart Rhythms

Treatment depends on the type of arrhythmia, its severity, and the patient’s overall health. Many patients benefit from medications that help regulate heart rhythm or control heart rate. These therapies are often used to reduce symptoms and lower the risk of complications.

In some cases, advanced procedures may be recommended. Catheter-based treatments can target the areas of the heart responsible for abnormal electrical signals. For patients with more persistent or complex arrhythmias, implantable devices may be used to help maintain a stable rhythm and monitor heart function.

Lifestyle factors also play a role in managing arrhythmias. Addressing underlying conditions such as high blood pressure, maintaining a balanced diet, and engaging in appropriate physical activity can support overall heart health.

Ongoing Care and Monitoring

Managing irregular heart rhythms often requires ongoing evaluation. Regular follow-up visits allow Dr. Radwaner to monitor progress, adjust treatment, and respond to changes in symptoms. Early intervention and consistent care can help reduce complications and improve quality of life.
