Chrishan J. Nalliah is a cardiologist based on Hawkesbury Road in Westmead, NSW 2145.
Heart problems can feel scary, even when they’re not the most serious case. Dr Nalliah helps people who are dealing with things like an irregular heartbeat, episodes where the heart suddenly races, or slower and blocked heart rhythms. In many cases, the goal is to make symptoms easier to live with and help the heart work as well as it can.
Appointments may be for atrial fibrillation, sick sinus syndrome, heart block, ectopic heartbeats, or other rhythm issues. Some people come in after an ECG finding, while others are seen because they’ve had palpitations, dizziness, fainting, shortness of breath, or chest discomfort. At times, problems can also link in with heart failure or cardiomyopathy, where the heart muscle or pumping isn’t behaving normally.
Dr Nalliah also looks after people with conditions that can affect the heart’s rhythm over time, including obstructive sleep apnoea and obesity. Treating these can make a real difference, especially for people who keep getting rhythm problems.
When medicines aren’t enough, care may include options such as cardiac ablation. Cardiac ablation is used for certain rhythm problems, like atrial fibrillation and some types of supraventricular tachycardia. It can also be considered for ventricular tachycardia and other rhythm patterns, depending on what the person has going on.
People can also be referred after concerns around cardiac arrest or ventricular fibrillation. These situations need careful follow-up, and the plan is usually built around what caused the event, what the heart looks like, and how the person is doing day to day.
Through ongoing reviews, Dr Nalliah works with patients to understand their symptoms and the options available. That might mean adjusting treatment, monitoring progress, or arranging follow-up tests. The focus stays practical: getting answers, reducing risks, and supporting a steady, safer way forward.
For anyone in the Westmead area looking for cardiology care for rhythm problems, valve-related issues such as mitral valve prolapse, or heart conditions that affect day-to-day health, Dr Nalliah provides a calm and clear approach.
