The Care You Deserve

For years, patients have depended on me to provide this valuable service. I offer this and other specialised options and clinical assessments to anyone in need of a Cardiologist they can trust. I’m Dr Krys Milburn at South Island Heart, and I’m dedicated to building long-lasting relationships based on trust and medical integrity with every single patient.


If you would like to reduce your chances of having a heart attack as much as possible, then you can take several steps to achieve your goal of good health. While genetics play a significant role in your risk level, your lifestyle is just as important – and entirely within your control. You should also visit a cardiologist for an assessment, and that’s where South Island Heart can help.

Doctor's Appointment

At South Island Heart, patients can access a wide range of services, such as:

  • Cardiology consultation. A cardiology consultation is a good idea for anyone, especially if you have experienced any symptoms you’re concerned about (or a doctor has told you that you should see a cardiologist). We have provided cardiac consultations in New Zealand for years. If you need a clinical assessment from an experienced and skilled cardiologist that you can trust, we encourage you to get in touch and schedule your consultation today.

  • Cardiac stress test. A treadmill exercise stress test is an effective way to evaluate the health of your heart and how well it handles physical activity. Exercise allows doctors to detect abnormal heart rhythms and identify the presence of heart disease in New Zealand. During a stress test, you will walk in place on a treadmill while the speed and incline increase. Your heart will be monitored the entire time to determine how well it responds to the stress of exercise.

  • Coronary angiography stenting. When cholesterol plaque builds up within your artery walls over time, it causes the artery to narrow and reduces blood flow. A sudden change in this plaque can cause angina (chest pain) or even a heart attack in NZ. We can check for this narrowing and, if necessary, treat it with a stent designed to widen these narrow areas and allow blood to flow freely through the artery.

  • Hypertension evaluation. Hypertension, or high blood pressure, can damage your heart over time. Uncontrolled hypertension can eventually lead to problems such as heart attack, stroke, or heart failure. It may also cause peripheral artery disease, which is a narrowing of the arteries in the head, arms, stomach, or legs. It’s important to monitor your blood pressure and take action if it becomes too high. A treatment plan for high blood pressure may include self-monitoring, lifestyle changes such as diet and exercise, or prescription medications.

  • Echocardiography. An echocardiogram is an imaging technology that uses ultrasound to produce images of your heart. We use this diagnostic test to examine your heart and blood supply to the heart, check its size and structural health, determine how well it contracts, and ensure that each heart valve functions properly. An ultrasound probe will be placed on your chest during this test, and harmless, painless sound waves are used to create the images. The images will be displayed and digitally recorded with the help of a special monitor.


If you have already had a heart attack, you are more likely to have another one than someone who has never had one. Even if you haven’t had a heart attack, there are things that you can do to minimise your risk. Give yourself the best odds of staying healthy by avoiding these common mistakes.

  • Not exercising. One of the best things that you can do for your heart is getting regular exercise. Physical activity can help you mitigate the risks associated with excess weight, high cholesterol, hypertension, and diabetes. Be sure to ask your doctor what type of exercise is appropriate for you.

  • Eating an unhealthy diet. It can be extremely challenging to change your diet. However, eating a healthy diet is a key factor in keeping your heart attack risk low. Strive for a healthy, balanced diet of natural, low-fat foods. A healthy diet will also help you control your weight, further lowering your risk.

  • Assuming that all heart attacks are the same. If you know someone who had a heart attack, you may be tempted to compare your risk to theirs. For example, if your uncle spent his life eating healthy foods and jogging every day and then had a heart attack, you may think that changing your own lifestyle isn’t worth the trouble. However, everyone has a different genetic makeup and unique risk factors.

  • Not seeking medical attention in an emergency. When you experience chest pain in NZ and aren’t completely sure of the cause, the right course of action is to seek emergency medical care. Don’t assume that it will go away, and don’t feel silly for getting medical attention that you don’t need. It’s better to be safe than sorry. Don’t take chances or waste time; call for an ambulance right away.

If you have been diagnosed with a heart murmur in NZ, then you may be wondering exactly what a heart murmur is and what it means for your overall health. A heart murmur is the sound of blood flowing abnormally, such as through an abnormal artery or faster than normal. Many heart murmurs are harmless; in fact, children often outgrow them and lead completely normal lives. However, there are exceptions, and some heart murmurs will require treatment, depending on their underlying cause. If your heart murmur is caused by a heart valve disease, for example, then you may need treatment such as:

  • Medication. Several types of medicine are appropriate for someone with a heart murmur, including blood thinners and statin medications designed to reduce the risk of clots or lower cholesterol.

  • Diuretics. Diuretics, also known as water pills, work by removing excess fluid from your body. This action can help treat conditions that might exacerbate a heart murmur, such as hypertension.

  • Surgery. In some instances, surgery may be required to repair the damaged valve. Procedures that your doctor might recommend include balloon angioplasty, annuloplasty, valve leaflet repair, and valve replacement.
