Heart Conditions We Treat
Heart rhythm disorders are common, and most are treatable once the exact rhythm has been pinned down. Been told you have one, or think you might? Dr Paul Lim subspecialises in heart rhythm — the guides below set out what each condition is, and what can be done about it.

Detailed Condition Guides
In-depth, doctor-reviewed guides to the heart rhythm conditions Dr Lim treats most often.
Heart Palpitations
The feeling of a fluttering, pounding or racing heartbeat — what it means, when to worry, and the tests that find the cause.
Irregular Heartbeat (Arrhythmia)
The broad family of heart rhythm disorders — what they are, why they happen, and when to seek help.
Atrial Fibrillation (AFib)
The most common sustained arrhythmia — symptoms, stroke risk and modern treatment.
Atrial Flutter
A fast, organised rhythm with a sawtooth ECG — often treatable with a single targeted ablation.
Tachycardia (Fast Heart Rate)
When the heart beats too fast — including SVT and ventricular tachycardia, their symptoms and treatment.
Bradycardia (Slow Heart Rate)
When the heart beats too slowly: sinus node problems, sick sinus syndrome, and when a pacemaker is the answer.
Heart Block (AV Block)
First, second and third degree block, plus bundle branch block — what each grade means on an ECG and when it needs treating.
Risk Factor Guides
The conditions that drive coronary artery disease over time — often silent, and worth understanding before they cause symptoms.
Coronary Artery Disease
Narrowed heart arteries and angina — what the symptoms feel like, the tests that find it, and what treatment achieves.
High Cholesterol
Almost always silent — the visible signs that do exist, what they mean, and the blood test that settles it.
High Blood Pressure
What 140/90 actually means, why it rarely causes symptoms, and what to do about a raised reading.
Low Blood Pressure
Why 90/60 is not a diagnosis, what makes a low reading matter, and the drop on standing that does have a definition.
Structural Heart Guides
Conditions of the heart muscle and its pumping strength, and how they are measured and treated.
