The Auckland Heart Group is New Zealand's largest private cardiology group, with extensive subspecialty expertise in the diagnosis and treatment of all forms of heart disease, in children as well as in adults.
Our seamless and comprehensive cardiac service can provide excellent care and advice in the areas of general and preventive cardiology, such as hypertension (high blood pressure) and raised cholesterol, through to the management of heart attack and its complications.
Whether the problem is an asymptomatic heart murmur that may indicate significant valvular heart disease, the need to differentiate benign palpitations from a serious arrhythmia, the management of heart failure, or investigation of chest pain that could be angina pectoris, the Auckland Heart Group can help.
We offer a caring and compassionate service allied with state of the art equipment and cardiologists who are among the best in their subspecialty fields.
