Cardiac ablation is a procedure that works by scarring or destroying tissue in your heart that triggers or sustains an abnormal heart rhythm.

Atrial Fibrillation

Atrial fibrillation is an irregular heartbeat, also called an arrhythmia, that can increase your risk of heart failure, stroke, blood clots and other heart conditions.

CABG - Coronary Artery Bypass Grafting

Coronary artery bypass grafting (CABG) is a type of surgery that improves blood flow to the heart. Surgeons use CABG to treat people who have severe coronary heart disease (CHD). These arteries supply oxygen-rich blood to your heart.

Cardiac Conditions in Children

It’s not just adults who experience heart disease. Children can experience a variety of heart conditions, including heart valve disorders, arrhythmias and single ventricle defects. Some heart conditions can actually be diagnosed during pregnancy with a prenatal echocardiogram.

Cardiac Rehabilitation

Patients that have experienced a heart attack need a very specialized and carefully monitored exercise rehabilitation program, along with close monitoring of medications.

Congestive Heart Failure

Heart failure is when the heart muscle cannot pump blood through the body well enough to provide adequate blood and oxygen to the body.

Congestive Heart Failure Treatment

Congestive heart failure (CHF) is a very common condition with which millions of North Americans are diagnosed each year. It is the stage at which “heart failure” has led to a build up of fluid around the heart. This build up affects the efficiency of the heart muscle to pump blood throughout your body. Early treatment and management of congestive heart failure can have very positive affects on this condition, slowing its progression and possibly reversing it entirely.

COPD & Heart Failure

Chronic obstructive pulmonary disease (COPD) is commonly associated with heart failure. While chronic obstructive pulmonary disease and heart failure are two different conditions, they can both cause breathing problems.

COPD & Lung Health

Chronic obstructive pulmonary disease (COPD) is a chronic lung disease that has many causes including smoking and genetic factors. There are several types, including bronchitis and emphysema.

COPD (Chronic Obstructive Pulmonary Disease)

Chronic obstructive pulmonary disease (COPD) is commonly associated with the narrowing of the breathing tubes within the lungs and damage to the gas exchange units called alveoli. The exact cause of COPD is unknown however there is a complex relationship between ones genetics and various environmental factors such as long-term smoking, pollution, poor nutrition, poor exercise and chronic chest infections.

Defibrillators (AEDs and ICDs)

An implantable cardioverter-defibrillator or automated implantable cardioverter defibrillator is a device implantable inside the body, able to perform cardioversion, defibrillation, and pacing of the heart.

Genetic Conditions

Inherited heart rhythm conditions can affect the electrical signals and sometimes muscle function of the heart.

Heart Attack

A heart attack happens when muscle tissue in the heart is denied the flow of oxygen-rich blood due to a blocked artery. It is considered a medical emergency.

Heart Disease

High cholesterol, smoking, obesity and lack of physical activity are risk factors for heart disease. Heart disease can be prevented.

Heart Failure & Exercise

It’s essential for patients with heart failure to exercise, but it can be difficult to determine what type is the most effective and safe for you. Before you start any kind of exercise program, talk to your healthcare provider.

Heart Failure & Sodium Quiz

While your body needs some sodium, too much causes your body to retain fluid and forces your heart to work harder. If you have heart failure, this can weaken the heart muscle. A low-sodium diet can help minimize the extra fluid and prevent heart problems.

Heart Failure Diagnosis

It’s important to see your healthcare provider for regular checkups, and especially if you're experiencing the potential symptoms of heart failure, which include shortness of breath, coughing and fatigue.

Heart Surgery

Cardiothoracic surgery involves the surgical treatment of organs inside the thorax (chest), including conditions of the heart and lungs.

Heart Valve Replacement

Heart valve surgery and procedures are performed to repair or replace a valve in the heart that is not working properly because of valvular heart disease (also called heart valve disease). Heart valve surgery is open-heart surgery through the breastbone, into the chest.

La fibrillation

Meal Planning for Obesity

While there is no one diet for obesity, creating a healthy meal plan can definitely help in your weight loss journey. Research shows that people who planned meals are less likely to be overweight or obese.

Neurology of a Stroke

A neurologist is a medical doctor who has taken specialty training in the diagnosis and treatment of nervous system disorders including stroke.


A healthy heart can be impacted by diet and nutrition. Watching your intake of LDL cholesterol and sodium can be important.

Obesity & Mental Health

Obesity is an incredibly common health condition that occurs when a person has accumulated so much body fat that it can negatively affect their health. According to studies, nearly 30% of people worldwide are overweight or obese—it’s become an epidemic.

Obesity Heart Health

Obesity is a chronic and often progressive condition, similar to diabetes or high blood pressure. Obesity is characterized by excess body fat that can threaten or affect your health.

Obesity Treatments

Obesity is a chronic, lifelong disease. It can be difficult to treat, because a person needs to both restrict calorie intake and be more active. Some patients also benefit from weight loss medications.


A pacemaker is a small device that's placed in the chest or abdomen to help control abnormal heart rhythms.

PCI - Coronary Angioplasty

Angioplasty is the technique of mechanically widening a narrowed or obstructed blood vessel; typically as a result of atherosclerosis. Tightly folded balloons are passed into the narrowed locations and then inflated to a fixed size.

Rehabilitation Exercises

Patients that have experienced a heart attack can benefit from a rehabilitation program that incorporates exercises patients can do at home.

Sleep Apnea

Sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts. If you snore loudly and feel tired even after a full night's sleep, you might have sleep apnea.

Smoking Cessation

There are a variety of smoking cessation tools including prescription drugs and nicotine replacement aids.


A stent is a small wire mesh tube that is placed into an artery of the heart when narrowing takes place due to plaque build up.


A stroke can lead to a sudden diminution or loss of consciousness, sensation, and voluntary motion caused by rupture or obstruction (by a clot) of a blood vessel of the brain.

Sudden Death

Sudden death is actually quite common. Thirty thousand Canadians die suddenly every year, and 90 percent of people who collapse and die can’t be saved. A patient suddenly drops to the floor and the heart rhythm increases – often up to 200 or 300 beats a minute.

SVT - Supraventricular Tachycardia

Supraventricular tachycardia (SVT), also called paroxysmal supraventricular tachycardia, is defined as an abnormally fast heartbeat. It's a broad term that includes many forms of heart rhythm problems (heart arrhythmias) that originate above the ventricles (supraventricular) in the atria or AV node.

Types of Cardiac Testing

These are just a few of the tests that have been used to diagnose heart and blood vessel disease (cardiovascular). For more information, talk to your cardiologist or other healthcare provider.
