Many things can cause signs and symptoms of bradycardia. It's important to get a prompt, accurate diagnosis and appropriate care. See your health care provider if you are concerned about a slow heart rate.
Treatment for bradycardia depends on the severity of symptoms and the cause of the slow heart rate. If you don't have symptoms, treatment might not be necessary. Bradycardia treatment may include lifestyle changes, medication changes or an implanted device called a pacemaker.
Bradycardia (brad-e-KAHR-dee-uh) is a slow heartbeat. The heart rate is less than 60 beats a minute. Fast heartbeat, called tachycardia. Types of tachycardias include: Atrial fibrillation (AFib). Chaotic heart signaling causes a rapid, uncoordinated heartbeat. AFib may be temporary and start and stop on its own. But some episodes may not stop ...
Causes. Tachycardia is an increased heart rate for any reason. If a fast heart rate is caused by exercise or stress, it's called sinus tachycardia. Sinus tachycardia is a symptom, not a condition. Most heart conditions can lead to different forms of tachycardia. Irregular heart rhythms, called arrhythmias, are one cause.
Tachycardia-bradycardia syndrome. The heart rate alternates between unusually slow and fast rhythms, often with a long pause between heartbeats.
Some heart conditions that can lead to low blood pressure include extremely low heart rate (bradycardia), heart valve problems, heart attack and heart failure. These conditions prevent the body from quickly pumping more blood when standing up.
Causes. To understand the causes of atrial fibrillation (AFib), it may be helpful to know how the heart typically beats. The heart has four chambers: The two upper chambers are called the atria. The two lower chambers are called the ventricles. Inside the upper right heart chamber is a group of cells called the sinus node.
The most common cause of hypothyroidism is an autoimmune disease called Hashimoto's disease. Autoimmune diseases happen when the immune system makes antibodies that attack healthy tissues. Sometimes that process involves the thyroid gland and affects its ability to make hormones.
Premature ventricular contractions often cause few or no symptoms. But the extra beats can cause unusual sensations in the chest, such as: Fluttering; Pounding or jumping; Skipped beats or missed beats; Increased awareness of the heartbeat
If you have bradycardia, your heart beats fewer than 60 times a minute. Bradycardia can be a serious problem if the heart rate is very slow and the heart can't pump enough oxygen-rich blood to the body.
