Arrhythmia is a heart rhythm disorder that causes the heartbeat to become too fast, too slow, or irregular. This condition occurs due to abnormalities in the heart’s electrical system, which is responsible for regulating heart rhythm. In some individuals, arrhythmia may cause mild symptoms, but in certain cases, it can lead to severe and potentially life-threatening conditions.
If left untreated, arrhythmia can increase the risk of serious complications such as heart failure, stroke, loss of consciousness, and sudden cardiac arrest. Therefore, proper medical evaluation and timely treatment are essential when someone begins experiencing symptoms such as palpitations, chest discomfort, or an abnormal heart rhythm.
Mandaya Royal Hospital Puri offers a modern solution for arrhythmia treatment through cardiac ablation procedures. This treatment is performed by a consultant cardiologist specializing in arrhythmia, Dr. Sebastian Andy Manurung, MD, Sp.JP, Subsp. Ar(K), FIHA, who has extensive experience in managing various types of heart rhythm disorders. Cardiac ablation aims to correct the source of abnormal electrical signals so that the heart rhythm can return to a normal and stable pattern.
This condition was experienced by a female patient who suddenly developed episodes of heart palpitations. She visited Mandaya Royal Hospital Puri and underwent a cardiac ablation procedure performed by Dr. Sebastian. What was her experience like?

Cardiac Arrhythmia Treatment Options
Arrhythmia symptoms experienced by the patient
The female patient from Jakarta initially experienced sudden episodes of heart palpitations. The sensation felt uncomfortable and frightening, as her heartbeat became extremely rapid and unlike her usual rhythm. These symptoms appeared unexpectedly and significantly interfered with her daily activities.
When the symptoms occurred, the patient underwent a medical examination and was diagnosed with cardiac arrhythmia. This diagnosis caused further concern, as she realized that heart rhythm disorders can have serious consequences if not treated promptly.
Decision to undergo cardiac ablation and the procedure
After consulting with the doctor, the patient received a detailed explanation of her arrhythmia condition and the available treatment options. Initially, she felt hesitant and afraid to undergo a cardiac ablation procedure. However, concerns about the potential risks of untreated arrhythmia eventually strengthened her decision to proceed with the treatment.
This decision was made after the patient understood that cardiac ablation directly targets the source of abnormal heart rhythms and offers better long-term recovery outcomes.
The cardiac ablation procedure was completed in a relatively short time. During the procedure, the patient experienced mild discomfort, but the pain was minimal and tolerable. After the procedure, the recovery process progressed smoothly.
Shortly after the treatment, the frequent palpitations she had previously experienced no longer occurred. The patient was also able to gradually resume daily activities without significant complaints, including walking and performing light activities.
Patient condition after the procedure
Following the cardiac ablation, the patient’s condition showed significant improvement. Her heartbeat felt more stable, and the palpitations were no longer present. She also felt calmer and more comfortable knowing that her heart rhythm disorder had been properly treated.
This experience demonstrates that cardiac ablation can be an effective solution for patients with arrhythmia, especially when performed by an experienced specialist at a well-equipped medical facility such as Mandaya Royal Hospital Puri.
