What is a Cardiologist
A cardiologist is a physician with special training and skill in finding, treating and preventing diseases of the heart and blood vessels. Cardiologists work with patients to treat conditions including coronary artery disease, heart attack, atrial fibrillation and irregular heart rhythm. A cardiologist can help you manage risk through nutrition, exercise and lifestyle changes. If you’ve had a cardiac event, a cardiologist will play a role in recovery after surgery, cardiac rehab and heart medications.
Dr. Shubhayan Sanatani, MD, FRCPC, Pediatric Cardiologist and Electrophysiologist, talks about heart murmurs in children.
A heart murmur is one of the most common reasons for being sent to a pediatrician or a pediatric cardiologist. A heart murmur is a sound, and it’s a sound that’s usually heard by a doctor or a nurse at a health encounter. There are a lot of misconceptions about what a heart murmur actually is. Some people think it means there’s a hole in the heart, or a skipped beat. It’s not a diagnosis, but it’s just a sound.
Most children can have a heart murmur heard at some point in their lives. And there’s lots of reasons for this. Their chest walls are thin, blood is moving quickly, the structures are a bit smaller, so it’s very common to hear this normal blood flow sound. In fact, most heart murmurs are just that; they’re just the sound of normal blood flow in otherwise healthy children.
A heart murmur in and of itself doesn’t really have symptoms. A heart murmur rarely means there’s underlying heart disease. And that heart disease may be associated with symptoms. Particularly in young children, in infants, difficulties with feeding, or growing, breathing difficulties, those can be signs of heart disease. And sometimes that heart disease presents with a heart murmur—the sound of the abnormal blood flow in this case. Again, it’s important to remember that most heart murmurs represent normal blood flow in otherwise healthy children.
A heart murmur will often be picked up as an incidental finding. A child may be at a routine health appointment. A common scenario is during another illness, so a viral illness—particularly one that is associated with a fever—a murmur might be heard at that time. Once a heart murmur is heard, it’s common to be referred to a pediatrician or a pediatric cardiologist, who may in turn order additional investigations.
Since most children with heart murmurs don’t have any heart disease at all, there may not be a need for any testing. If the heart murmur is found to be associated with heart disease, there may be treatment required. Many forms of heart disease don’t require any treatment at all. These will be the things that you discuss with your pediatric cardiologist. If you do have any questions about heart murmurs, your family doctor or your pediatrician will be happy to talk to you.

Dr. Andrew Krahn, MD, FRCPC, Cardiologist, and Julie Hathaway MSc, CGC, CCGC, Genetic Counsellor, discuss a genetic cardiac condition called Brugada Syndrome (Cantonese Subtitles).
Dr. Andrew Krahn: 布魯格達氏症候群是心臟電流出現異常，這些異常可以在心電圖看見，這些異常會被注意到因為它們不沈常。
Julie Hathaway: 很多患者能從心電圖被診斷患有布魯格達氏症候群，有時候心電圖清楚顯示出典型的布魯格達氏波型，有時候顯示出其他布魯格達氏波型，比如布魯格達氏症候群型II。
Dr. Andrew Krahn: 布魯格達氏症候群的治療方法有兩種，因大部分患者不會因為布魯格達氏症候群引起身體不適，他們可以平常注意一些事情，比如避免服用一些藥物，發熱時儘快控制情況，和發生頭暈和抽搐的話告知家庭醫生。
如果您或您的家人擔心有可能患有布魯格達氏症候群，請跟您的家庭醫生商討，您的家庭醫生可能會把你推薦給心臟科專科醫生。 講師: Dr. Andrew Krahn
