Symptom of tachycardia include awareness of a rapid heartbeat, commonly called "palpitations." Other symptoms may include shortness of breath, dizziness, actual syncope (fainting), chest pain, and severe anxiety
Cerebral Dyrhythmia Symptoms
if a person experiences cardiac arrhythmias and low levels of potassium are present the person has a condition called hypokalemia.
As with most electrolyte imbalances the symptoms of hypokalemia, or low potassium, are tied directly to its function in the body. A normal potassium level is anywhere from 3.5-5.3 mg/dL in human blood. Anything less than this can be called hypokalemia. Symptoms are hypertension, cardiac dysrhythmia, muscle weakness, and constipation. If allowed to continue it may progress symptoms will progress to decreased reflex response, paralysis, tetany, and cardiac arrest. It is also important to note that symptoms are not typical until the potassium level is some where around 2.6.
cardiac arrhythmia
Nothing!
A cardiologist will run tests on your heart to find the reason for the abnormal beat if you are diagnosed with dysrhythmia.
The most common abnormal heart rhythm preceding cardiac arrest is ventricular fibrillation. In this dysrhythmia, the ventricular walls contract randomly and rapidly, and do not effectively pump blood.
Individuals with cardiac problems can manifest a variety of symptoms depending on the nature of the problem. For example, palpitations, chest pain, shortness of breath, dizziness, and fainting, for example, are all possibilities.
Arrhythmia
Cardiac rehabilitation is prescribed to control symptoms, improve exercise tolerance, and improve the overall quality of life in these patients.
Cardiac asthma is wheezing, coughing, and shortness of breath due to congestive heart failure. Cardiac asthma was given the name because its symptoms mimic those of ordinary asthma.
Symptoms are often vague and include (in order of frequency) fatigue, headache, dizziness, sleep disturbances, cardiac symptoms, apathy, nausea, and memory disturbances.
