![]() In some cases, atrial fibrillation can be corrected with medication or by administering a shock to a sedated patient's heart. ![]() Kusumoto says atrial fibrillation decreases the heart's blood pumping efficiency and puts a patient at higher risk for blood clots, heart failure, and stroke. Other times, people just notice that they're more short of breath when they walk upstairs." Fred Kusumoto is an electrophysiologist at Mayo Clinic.įRED KUSUMOTO, M.D.: "In some cases people feel their heart palpitating or beating very, very fast or a flip-flop in their heart or chest area. Atrial fibrillation interrupts this regular beat.įRED KUSUMOTO, M.D.: "In atrial fibrillation, instead of the atria squeezing in a normal regular fashion, the atria beat irregularly and chaotically." Most people who have ventricular fibrillation have an underlying heart disease or have experienced serious trauma, such as being struck by lightning. This serious problem can lead to death if the heart rhythm isn't restored within minutes. Rapid, chaotic electrical signals cause the ventricles to quiver instead of contracting in a coordinated way. Supraventricular tachycardia causes episodes of a pounding heartbeat (palpitations) that begin and end abruptly. Supraventricular tachycardia is a broad term that includes arrhythmias that start above the ventricles. ![]() But episodes lasting more than a few seconds can be life-threatening. Ventricular tachycardia episodes may be brief and last only a couple of seconds without causing harm. The rapid heart rate doesn't allow the ventricles to fill and squeeze (contract) to pump enough blood to the body. This type of arrhythmia starts in the lower heart chambers (ventricles). People who have atrial flutter also often have atrial fibrillation at other times. Episodes of atrial flutter may go away themselves or may require treatment. Atrial flutter is similar to A-fib, but heartbeats are more organized. A-fib may be temporary, but some episodes won't end unless treated. Chaotic, irregular electrical signals in the upper chambers of the heart (atria) cause a fast heartbeat. This is the most common type of tachycardia. Common types of tachycardia caused by irregular heart rhythms (arrhythmias) include: ![]() Other types of tachycardia are grouped according to the part of the heart responsible for the fast heart rate and the cause. Sinus tachycardia refers to a typical increase in the heart rate often caused by exercise or stress. There are many different types of tachycardia. Treatment for tachycardia may include specific maneuvers, medication, cardioversion or surgery to control a rapid heartbeat. But if left untreated, some forms of tachycardia can lead to serious health problems, including heart failure, stroke or sudden cardiac death. In cases where arrhythmia is occurring and irregular signals are being sent causing disorders – such as a drop in blood pressure or symptoms that are unresponsive to medication -, these emergency cases may have their electrical impulses reset via a process called a “cardioversion”.Tachycardia may not cause any symptoms or complications. The treatment involves inserting a device into the upper chamber of the heart (Left Atrium), which is most commonly affected by thrombosis. There is also a non-medicated form of treatment available that can prevent thrombosis. Surgery to repair the muscle tissue located in the upper chamber of the heart which is responsible for sending the irregular signals.Installation of a pacemaker that interrupts any irregular impulses transmitted to the heart and replaces them with its own, regular signals.Hence, if any signals of this condition are displayed, doctors will utilize this form of medication. When a clot is forced out of the heart, it has the potential to affect another vital organ, potentially leading to full or partial paralysis from embolic stroke. Anticoagulant medication, because arrhythmia patients often suffer thrombosis in the upper chamber of the heart (Left Atrium).Medication that regulates the irregular heartbeat to ensure the heartbeat remains normal, preventing further irregular heartbeat.Medication which controls the heart rate when resting or during exercise.The following forms of treatment may be utilized: Targeting the symptoms is the main objective of treatment, together with reducing the chance of any complications arising from arrythmnia.
