The cardiovascular system is the first to become functional in the embryo. As early as the third week of development, blood circulation begins, marking a crucial step for the embryo’s growth and development. This primitive system ensures the delivery of nutrients and oxygen essential for its rapid development.
The circulatory system begins to form very early during embryonic development, just a few days after the fertilization of the egg by the sperm. It is the first functional system to develop, as it is crucial for delivering the nutrients and oxygen required for the embryo’s rapid growth. This early formation is a complex and fascinating process that marks the initial stages of life.
An automated external defibrillator, commonly referred to as an “AED,” is a device used to assist someone who has collapsed, is unresponsive, and may require emergency intervention to save their life.
This small, portable device is battery-powered and incredibly user-friendly. Anyone can operate it, regardless of whether they have received prior training in cardiopulmonary resuscitation (CPR).
As the New Year begins, everyone rushes to exchange warm wishes. Among the most common, you often hear: “Good health!”
But beyond this kind sentiment, take a moment to reflect: are you truly giving your well-being the attention it deserves?
Wishing alone isn’t enough. Preserving your health requires concrete actions and the determination to turn words into deeds.
Every year, it’s the same marathon: work demands, frantic last-minute gift shopping, the whims of Mother Nature, and of course, countless celebrations.
Just thinking about it can take your breath away! But how is your heart holding up through it all?
The pacemaker implantation procedure is relatively straightforward and generally well-tolerated. A small incision is made in the chest, usually on the left side, to create a pocket under the skin to house the pacemaker’s casing.
Takotsubo syndrome is a heart condition classified under the family of cardiomyopathies. Also known as broken heart syndrome, apical ballooning, or stress-induced cardiomyopathy, this disorder is characterized by a temporary weakening of the heart muscle, often triggered by intense emotional or physical stress.
The pacemaker, also known as a cardiac stimulator or “battery,” can be compared to a sophisticated miniature computer implanted under the skin. Its primary mission is to ensure a regular and efficient heartbeat.
It continuously captures the heart’s electrical signals and, much like a GPS, tracks the trajectory of impulses through the various components of the heart’s electrical system. By analyzing this data in real-time, it determines whether the natural system is functioning properly. In case of failure, it steps in by delivering the necessary impulse to maintain an optimal heart rhythm.
Heart failure is a chronic condition. Although advancements in treatment have improved outcomes, it remains a serious condition, particularly for those with a reduced ejection fraction.
Worldwide, millions of people are affected by this disease. In Canada, approximately 1% of the adult population lives with this condition, and its prevalence increases to 10% among individuals over the age of 65.
When the heart rate drops below 60 beats per minute, it is referred to as bradycardia. This slower rate can be a natural response or, in some cases, a sign of a rhythm disorder.
This site is intended to provide information and make cardiology comprehensible for all patients; it is not a substitute for a doctor. It does, however, enable a better understanding of how the heart works, the many heart diseases that exist, the tests required to reach a diagnosis, and the drugs and other methods used to treat them.
