Electrocardiogram (ECG or EKG): Measures the electrical activity of the heartbeat to provide two kinds of information. First, by measuring time intervals on the ECG, a doctor can determine how long the electrical wave takes to pass through your heart.
How do you know if you have an electrical problem with your heart?
You may feel palpitations: a rapid heart rate, skipped beats, thumping or pounding in your chest. Cardiac arrhythmias may make you feel anxious, nervous, dizzy, faint or short of breath. Cardiac arrhythmias often are controlled with medications. Your doctor may want to do tests, however, to determine other treatments.
How do you treat electrical problems in the heart?
With electrical cardioversion, a high-energy shock is sent to the heart to reset a normal rhythm. It is different from chemical cardioversion, in which medicines are used to try to restore a normal rhythm. Normally, a special group of cells begin the electrical signal to start your heartbeat.
Is electrophysiology same as EKG?
An electrophysiology (EP) study is a test of your heart’s electrical system. While an electrocardiogram (ECG) gives an overview of your heart’s electrical system, the EP study gives a more in-depth view. The test helps find out details about abnormal heart rhythms, called arrhythmias.
How long does an electrophysiology study take?
Tell your care team if you feel any pain. An EP study can take one to four hours. Your test may last longer if you’re also undergoing cardiac ablation.
What causes the heart’s electrical system to malfunction?
The problem: Over time, coronary artery disease, other heart diseases, diabetes and high blood pressure can weaken the heart. The heart’s ability to move blood through your body can also deteriorate suddenly after heart attack or infection.
What causes damage to the heart’s electrical system?
It can also be caused by problems with your heart function such as heart failure or leaky heart valves. Sometimes surgical intervention can also bring on this kind of problem. If these rhythm disturbances come from the upper chambers of the heart, they are called atrial arrhythmias (abnormal rhythms of the heartbeat).
Are you awake during cardioversion?
Because the shock would be painful for a patient who is awake, an intravenous medication is given to sedate the patient. Patients are asleep during the cardioversion and most do not remember the procedure.
What are the side effects of having your heart shocked?
Some other risks are:
- Problems breathing if you had medicine (sedation) to help you sleep during the procedure.
- Other less dangerous abnormal rhythms.
- Slow heart rate afterwards.
- Temporary low blood pressure.
- Heart damage (usually temporary and without symptoms)
- Heart failure.
- Skin damage/irritation.
How serious is a cardioversion?
A cardioversion is usually a safe procedure, and serious problems are unlikely. There is a small risk of blood clots that may travel from your heart to your body. Your medical team will be aware of this, and they’ll give you blood thinning medication to help prevent this from happening.
Are you asleep for an EP study?
EP studies are usually done with “conscious sedation” — that is, you will be given medication to relax you, but you will not be put under general anesthesia. Your doctor will talk to you ahead of time about the level of anesthesia planned for you. You will be awake, but you must remain still during the procedure.
What is an EP test?
An electrophysiological study (EP study) is a test used to evaluate your heart’s electrical system and to check for abnormal heart rhythms. Natural electrical impulses coordinate contractions of the different parts of the heart. This helps keep blood flowing the way it should.
How is electrophysiology test done?
An electrophysiology (EP) study is a test performed to assess your heart’s electrical system or activity and is used to diagnose abnormal heartbeats or arrhythmia. The test is performed by inserting catheters and then wire electrodes, which measure electrical activity, through blood vessels that enter the heart.
