Problems During Exercise for Cardiac Rehabilitation
In rare cases, a person in cardiac rehab may have problems
These problems may include:
A drop in blood pressure (hypotension), which may
Angina symptoms, such as chest pain or discomfort.
Exercise causes the heart to work harder. As the heart works harder, the heart
muscle needs more oxygen. If the narrowed heart vessels cannot provide enough
blood (and oxygen) to the heart, chest pain will result.
Heart attack (rare). But most studies have shown that
people who exercise are less likely to have a heart attack than people who do
Irregular heartbeats (arrhythmias) or sudden death
(rare). Exercise makes the heart muscle work harder, which in turn requires
more oxygen. If the narrowed heart blood vessels cannot provide enough blood
(with oxygen), the heart may develop irregular heartbeats. In rare cases, these
irregular heartbeats cause sudden death.
