Heart is the most important organ in the body. You are most likely familiar with the heart because of its beating which you most probably have heard through a stethoscope or you may have listened to someone else's heartbeat or may have put two fingers to your wrist or neck to feel your pulse. Your pulse is your heartbeat sensed in your arteries. Heartbeat is the relaxing and contracting of your heart's chambers: the upper chambers called the atria and the lower chambers called the ventricles.
Abnormal heart rhythms can lead to the occurrence of a life-threatening cardiac arrest in an individual. An individual would require immediate treatment for survival with the most appropriate treatment being proper application of the life-saving CPR techniques that comprise chest compressions and rescue breaths. For a CPR Overland Park Kansas, make sure to choose a certified training center such as the AHA certified CPR Kansas City. Classes are conducted through a series of audio and video lectures and hands-on practice.
So, the relaxing and contracting of the heart is stimulated by electrical impulses that travel through your ticker and regulate your heartbeat which begins in the sinoatrial (SA) node in the top of the right chamber (atrium) of the ticker. The electrical impulse travels through the muscles of both atria. The atria contracts (squeeze) in response. The electrical impulse is then picked up by the atrioventricular (AV) node, which is located between the atria and the ventricles. It is then passed to the fibers of the His-Purkinje system. The ventricles fill with blood from the atria before the electrical impulse causes them to contract. Once the ventricles contract, they force the blood out of the heart and to the lungs and the body.
Problems with the electrical system of the organ can be devastating. The primary reason behind the occurrence of a cardiac arrest is an abnormal heart rhythm that goes by the name of Ventricular Fibrillation. The number of heartbeats in a minute determines the heart rate. Normal heart rates change as a child matures.
1. A newborn baby’s ticker normally beats about 140 times per minute.
2. A five-year-old may have a rate of 100 beats a minute.
3. The normal rate of an older child or teenager at rest is about 70 beats a minute.
The heart range changes easily like during exercise, it beats faster. Arrhythmia (or dysrhythmia) occurs when the ticker beats irregularly. One type of arrhythmia, called sinus arrhythmia, is normal. Often an irregular heartbeat has no symptoms and goes unnoticed and sometimes it is detected during a routine wellness exam. It is advisable to go for regular checkups for staying safe.
At CPR Kansas City, you can either sign up for a course online or call on 913-998-7499. Online classes are also available which can be taken as per one’s convenience. But it is required for the individual to visit a training site for a skills test as no CPR course is complete without the conduction of a skills test.
