There are several symptoms which indicate cardiac disease but no symptom is cardiac specific. A doctor will assess the characteristics of a symptom such as relieving and aggravating factors to make a diagnosis.
Here are some common symptoms and their causes. This brief information should not be used for self diagnosis.
Causes of chest pain include coronary disease which reduces the blood flow to the heart, valve disease which reduces blood supply to the body and abnormal heart rhythms.
Cardiac chest pain often occurs on exertion.
This is an awareness of the heart beating. Usually, palpitations are not due to an abnormal heart rhythm but investigations are often required to exclude this.
“Tapping out” palpitations with your finger may help a doctor identify whether you have a heart rhythm problem because it gives an indication of heart rate and regularity.
The most common heart rhythm problem is atrial fibrillation.
Dizziness and Blackouts
Important causes include abnormal heart rhythms, cardiomyopathy and valve disease.
The duration of blackouts and the speed of subsequent recovery helps to make a diagnosis.
Symptoms are used to draw up a list of possible diagnoses and commonly, investigations are then carried out to make a final diagnosis.
