WHAT ARE PALPITATIONS?

Palpitations is a disagreeable awareness of the heart beat,often described as a pounding, stopping, jumping, or racing in the chest. The sensitivity of the nervous system determines whether or not the patient complains of palpitations, which are not related to the seriousness of the heart disease or the type of arrhythmia. When patients have a premature heart contraction(see figure94b ), they feel the post-extrasystolic beat,associated with a large stroke volume,which is due to the longer filling period in diastole. A patient may be aware of a cardiac arrhythmia(see figures 3, 5a, 7,14, 16) by detecting an uncomfortable sensation in the neck. They may complain when the heart beat is slow or fast, and when it regular or irregular.
