Causes of heart palpitations
There are a number of possible causes for a heart
palpitation, including:
- Thyroid disorders. Overactive thyroid or
hyperthyroidism is a typical cause of heart
palpitations.
- Mitral valve prolapse. This anatomical condition may
cause a distinctive murmur in the heart such as an abnormal
sounding heartbeat and can heart rate irregularities more
likely.
- Alcohol. It's supposed to relax you, but it doesn't
always work that way. Binge drinking is especially likely
to cause heart palpitations, even among the young.
- Anxiety and fear. It's very typical to feel heart
palpitations during a panic attack.
- Anemia
- Fever
- Hyperventilation and low oxygen levels in the
blood
- Stress. It's a hard driving, 24/7 world. Do you know
anyone these days who says..."I just don't know what to do
with all the time on my hands?"
- Stimulants. Caffeine is a risk factor, so are
antihistamines and over-the-counter diet aids. Nicotine and
certain illegal drugs like cocaine are risky too.
- Medications. Thyroid pills, asthma drugs, beta
blockers
- Physical Activity. Exercise is good, but it can be
overdone. Extremely intense workouts or competitive
activities can cause palpitations.
