So what do the Doctors mean when they talk about Heart Rhythms
What is a normal heart rhythm?
The heart is a muscle that pumps blood around the body. It needs an electrical supply. This is provided by a special group of heart cells called the sinus node, which is also known as your heart’s natural pacemaker.
The electrical signal produced by the sinus node makes your heart’s top chambers or atria contract and push blood through to the lower chambers or ventricles. When the impulses reach the ventricles, they contract to push the blood out of the heart and into the lungs and the rest of the body. These electrical impulses cause your heart to beat between 60 to 100 beats per minute (bpm).
The normal electrical pattern of your heart, is known as sinus rhythm, and can be recorded doing an electrocardiogram (ECG). You can measure your own heart rate and feel your rhythm by taking your pulse.
It’s normal for your heart to beat at different rates during the day. For example it will be slower when you are sleeping, resting or doing activites that do not require a lot of effort but may be faster when you are physically active such as when you are gardening, walking briskly, or running. Your heart rate might also be faster if you are anxious or excited.
