Heart palpitations can certainly be associated with shortness of breath, that is, the two symptoms together without a serious condition being present. That usually indicates that the irregularity of the heart rhythm is significant and may signal the need for a more comprehensive evaluation. In general, the more serious the symptoms, such as lightheadedness, loss of consciousness, chest pain, shortness of breath, the more seriously one needs to take the problem. If a patient has known heart disease such as a previous myocardial infarction, congestive heart failure CHF , hypertrophic cardiomyopathy HCM , and others, the symptoms of palpitations will require a thorough evaluation.
The irregularity of the heart rhythm per se usually does no damage to the heart itself. Patients with a very rapid heart over a long period of time do run a risk of developing enlargement and failure of the heart. We see heart enlargment with a very common cause of palpitations called atrial fibrillation. Patients can be in atrial fibrillation for many years without harm, but some patients with very little symptoms may have too rapid and irregular a rhythm present with symptoms of heart failure.
There may also be some increased risk of stroke because of blood clots that can form in association with atrial fibrillation. If someone has normal heart function and no evidence of structural heart disease, the PVCs are a nuisance, but benign. If the PVCs are so symptomatic as to be disruptive, try eliminating all of the factors such as caffeine, certain foods, stress, before considering any treatment with medications. When we do treat with medications, we usually try to use simple medications such as beta-blockers first before going on to specific anti-arrhythmic agents.
Very frequently, this is enough to improve patients' symptoms. In summary, PVCs are common. In the vast majority of cases, they are of no prognostic significance and frequently go away on their own without any treatment beyond being reassured by your doctor. The relationship between extra beats and exercise is a complicated one.
Many patients experience PVCs or palpitations before and after exercise, but not during exercise. When most patients start to exercise, their own heart rate rises and the PVCs or other extra beats disappear at higher heart rates. After exercise, the body's natural adrenalin level remains high for a period of time while the heart rate begins to go down during rest.
This period of time often permits the extra beats to come back, and sometimes their rate and frequency are higher than before exercise. If the other symptoms are mild or not present, usually there is not any reason for serious concern.
If other symptoms accompany the palpitations such as shortness of breath, chest discomfort, or severe lightheadedness or loss of consciousness, those symptoms with palpitations in any setting are a cause for concern and require further evaluation. An electrocardiogram is a representation of the electrical activity of the heart in multiple views.
It records about 12 seconds and patients with palpitations may or may not have an abnormality on their EKG during that time. That is why many physicians use ambulatory EKGs or Holter monitors to try to make a diagnosis. The other benefit of the standard EKG is that it may reveal evidence of other things that may be wrong with the heart such as an old heart attack or other electrical abnormalities that may provide important clues to an underlying diagnosis that the palpitations represent.
So an electrocardiogram is a valuable part of a heart evaluation, but is not particularly sensitive for detecting heart rhythm abnormalities. Other approaches include using a monitor that is hooked up quickly when symptoms occur but is otherwise carried in the pocket or purse for up to a month at a time.
This permits better correlation of the symptoms of palpitations and the heart rhythm at the time symptoms are being experienced. I have had a number of patients in my practice that had their first episode of rapid heart action and palpitation during pregnancy.
This is understandable in that the state of pregnancy causes significant shifts in blood volume and also puts a new stress on the heart that may bring out a tendency for rapid heart action that was not manifest prior to pregnancy. After the pregnancy, the patient may not experience palpitations or may begin to see palpitations occur under other stressful circumstances.
There certainly doesn't need to be anything wrong with the heart in order for palpitations to occur during pregnancy. One the other hand, women with a history of heart rhythm problems or syncope prior to pregnancy will often have a marked decrease in their symptoms during pregnancy as their cardiac output increases and blood volume increases. As for energy drinks? Energy drinks have also been shown to increase blood pressure and cause arrhythmias.
Alcohol is similar to caffeine—some people with arrhythmias can tolerate it, while others cannot. Alcohol is known to cause A-Fib, and recent studies have shown that both binge drinking and moderate drinking can raise your risk for atrial fibrillation. However, you do need to be extra careful. While the type of exercise you can do depends on your arrhythmia, Erica says that the rule of thumb is to choose cardio over weightlifting.
Instead, try cardio or yoga. The most important thing you can do is talk to your physician before starting an exercise program.
Being overweight or obese puts you at a higher risk for developing an arrhythmia or other heart problems. But there is one way you do not want to lose weight: diet pills or similar products promising rapid weight loss. QT prolongation occurs when the heart takes longer to contract and relax than it usually does.
Learn more about the effects of QT prolongation here. Dysrhythmia and arrhythmia are both terms doctors use to describe an abnormal heart rate. Types include bradyarrhythmia or supraventricular arrhythmia. Ventricular tachycardia VT causes the heart to beat at a rate of over beats per minute. VT causes include underlying heart disease. Learn more. Bradyarrhythmia means a slow heart rate with an arrhythmia. It is not always a cause for concern but may signal a serious underlying condition.
