Rythme cardiaque et ACS

September 20, 2019


 

There are many factors that can cause sudden cardiac arrest (SCA) . Although not all are related to heart function problems, the majority of them are. These causes are due to different heart rhythms: too fast, too slow or just irregular.

Most often, an abnormal heart rhythm is unpleasant but safe. Doctors will often tell you that you are safe to continue your normal daily life with or without medication. However, in some cases, those affected may require additional treatment to prevent a more serious event.

For those who want to know more about the different types of heart rhythms and how to treat them, we have prepared a practical guide that should help to see a little more clearly.

Qu’est-ce que le rythme cardiaque?

Clearly, the heartbeat is the way your heart beats. An ECG (electrocardiogram) is used to determine whether it is normal or abnormal and, depending on the result, whether you may need further treatment in the future. Abnormal rhythms are known as arrhythmia (sometimes called dysrhythmia) and come in many different forms with various symptoms.

Quels sont les différents types de rythme cardiaque ?

There are many types of heart rhythm disorders, ranging from minor disorders to those that can potentially lead to death. Some of the most common types of arrhythmia include:

  • Arterial Fibrillation: The most common type of arrhythmia, known as AF, characterized by the fact that your heart beats irregularly and faster than usual.
  • Ventricular Fibrillation (VF): the heart beats with fast and irregular electrical pulses . This makes the pumping cavities needlessly tremble in the heart (the ventricles), instead of pumping the blood properly. There are many early signs of VF, including some heart diseases.
  • Ventricular Tachycardia (VT): Abnormal electrical signals in the ventricles make the heart beat faster than normal, usually 100 beats or more per minute, without synchronization with the upper chambers .
  • Bradycardia: your heart beats slower than usual
  • Heart block: a disorder where your heart beats slower and can cause the person to collapse.
  • Supraventricular Tachycardia: a disorder occurring in the upper chambers of the heart, people who have it experience an abnormally fast heart rate.   

Quel rythme cardiaque est susceptible de déclencher un arrêt cardiaque soudain?

Of all the different types of heart rhythms, the most likely to cause ACS is ventricular fibrillation. It is the most deadly form of arrhythmia and refers to a pathology that causes disorganized electrical activity in the heart, which means it trembles rather than pumps. Ventricular fibrillation leads to a loss of consciousness that can lead to ACS.

Ventricular fibrillation can be caused by many factors, such as coronary heart disease, heart valve disease and long QT syndrome .

Que se passe-t-il lorsqu’une personne est victime d’un arrêt cardiaque soudain?

If a person experiences a sudden cardiac arrest , whether because of his or her heart rate or for any other reason, you must call 112 and begin CPR immediately. You should also ask someone to pick up the nearest defibrillator, as this will greatly increase the survivability of the victim.

An AED (Automatic External Defibrillator) will monitor the patient’s heart rate and attempt to restore the patient to normal through shock therapy. The defibrillator only shocks when it detects an arrhythmia, so there is no chance of accidentally shocking someone.

Comment savoir si je souffre de problèmes de rythme cardiaque?

You may have had some symptoms that worry you about heart rate. These may include palpitations, nausea, fainting and dizziness. If you have any of these symptoms, you should consult your doctor. They can refer you to a specialist for an ECG to record the electrical activity of your heart.

Comment pouvez-vous gérer votre rythme cardiaque?

If you are diagnosed with a heart rhythm disorder, your doctor will refer you to a specialist who can help you with your daily management.

Specialists will diagnose which type of disorder you have. It can be a Holter method (a process where a portable device is installed for 24 hours), a tilt table tilt test to reproduce the causes of your fainting, or even a surgical micromanipulation to find and treat the cause of your heart rhythm disorder.

Treatments vary depending on the type of disorder diagnosed, but may include pacemaker placement, defibrillator implantation, or treatment of heart failure.
