Heart palpitations are a feeling that your heart is beating too hard or too fast, skipping a beat, or fluttering. You may notice heart palpitations in your chest, throat, or neck.
Heart palpitations can be bothersome or frightening. They usually aren't serious or harmful, though, and often go away on their own. Most of the time, they're related to stress and anxiety or to consumption of stimulants such as caffeine, nicotine, or alcohol. Palpitations also often occur during pregnancy.
Follow the label directions on when and how to take nitrates. Take these drugs with or without meals. Medication tolerance can develop with these medications; this leads to their ineffectiveness. Talk with your doctor so you understand how to take these medications during the day. The number of doses you take each day, the time allowed between doses, and how long you need to take the medications will depend on your condition.
While taking these drugs, have your blood pressure checked regularly, as advised by your doctor.
Keep all appointments with your doctor and the laboratory so that your response to the drug can be monitored.
