Caffeine, Diet and Heart Arrhythmias
Caffeine is the most common
substance associated with heart
arrhythmias. Some people feel heart
palpitations when they drink coffee
or tea or eat chocolate. Red wine and
eating too much can bring about
symptoms in others. These rhythm
problems are rarely serious.
Substance Abuse: Drugs and Inhalants
Abusing legal or illegal drugs can
lead to dangerous arrhythmias.
Alcohol
Small amounts (less than one drink
a day) of alcohol may reduce the
incidence of heart problems and
increase “good” cholesterol (HDL
cholesterol). But, for some people,
alcohol can create heart rhythm
disturbances. Alcohol abuse is a
major risk factor for high blood
pressure, cardiomyopathy, heart
failure and stroke.
Tobacco
Tobacco causes more heart
and blood vessel disease, stroke
and heart-related deaths than all
illegal drugs combined. It contributes
to as much as one-third
of all cardiovascular disease.

Dietary Supplements & Over-the-Counter Medications
Some herbs and other substances
used in over-the-counter remedies
are believed to improve abnormal
heart rhythms. Others can make
them worse or interfere with heart
medications. Diet pills can be
especially problematic. Patients
should always consult their healthcare
provider before taking any
medication or supplement.
Prescription Drugs
While most medicines prescribed
by physicians are beneficial to
health, occasionally side effects can
be detrimental. Certain medications
commonly prescribed for arrhythmias,
heart disease and high blood pressure
can themselves cause heart problems,
including rhythm disturbances.
The best course of action for patients
is to be aware of symptoms and
work closely with a physician.
Substances in the Environment & Workplace
Hundreds of substances in the
environment can cause arrhythmias,
heart disease and death. In general,
people at greatest risk are those
who handle or come into contact
with dangerous substances in
the workplace.
A few of the substance that can
cause problems are: automobile
emissions, cigarette smoke, pollution
from industrial plants, paint thinners
and propane gas.
