You may need to make lifestyle changes, such as increasing your activity level or changing your diet (for example, limiting caffeine intake). The treatment for an arrhythmia depends on its cause. electrolyte imbalances, such as low potassium, calcium, and magnesium.Other factors can also cause alterations in your heart’s rhythm. Once your illness resolves, your heart rate typically returns to its normal rate. This may temporarily raise your heart rate. Having an illness or fever may temporarily cause sinus tachycardia. Your accelerated heart rate typically slows once you calm down. certain antiarrhythmic medications, such as digoxin and amiodarone, clonidine, and donepezilĪnxiety or other emotional distress can increase your heart rate as part of your body’s fight-or-flight response.beta-blockers, which treat high blood pressure.Medications that can cause your heart rate to decrease may include: other recreational drugs, such as cocaine.asthma medications, such as an albuterol inhaler.amphetamines, which are drugs that stimulate the brain.decongestants, such as phenylephrine or pseudoephedrine.Medications that may cause your heart rate to increase include: Some medications or substances may cause your heart rate to change. damage to your heart after a heart attack.heart failure, which happens when your heart can’t pump an adequate amount of blood.changes in your heart’s muscle after illness or injury.Some of these conditions may have other symptoms as well. Having a heart condition or an injury to your heart can lead you to develop an atypical heart rate. This plaque prevents oxygen and important nutrients from reaching your heart. Coronary heart diseaseĬoronary heart disease is a serious heart problem that occurs when cholesterol and other deposits block your coronary arteries. Over time, high blood pressure can lead to heart disease. It creates more resistance to blood flow and can affect how your heart works. High blood pressure means too much force is required to push the blood through your blood vessels. Several factors may cause an abnormal heart rhythm. In either case, when feeling your pulse, it may feel as though your heart pauses or skips a beat. It can occur in the atrium (premature atrial contraction) or in the ventricle (premature ventricular contraction). Premature contractionsĪ premature contraction is a beat that occurs early. It’s a serious condition that results in death if not immediately treated with defibrillation. This impairs the flow of blood from your heart and leads to cardiac arrest. Ventricular fibrillation is a life threatening arrhythmia in which the ventricles beat rapidly and erratically. medications, including certain blood pressure and antiarrythmic medications.Some athletes have slower heart rates because they’re in excellent physical condition, which isn’t usually the result of a heart problem. Bradycardia generally occurs when the electrical signals traveling from the atria to the ventricles become disrupted. If you have bradycardia, you have a slow heart rate (less than 60 bpm). In atrial flutter, your heart’s overall rhythm can be regular, but your heart rate is often fast.Ītrial flutter also increases your risk of stroke. It’s due to an abnormal circuit of electrical activity. It may occur in the left atrium as well.Ītrial flutter is a type of arrhythmia that originates in the atrium and results in rapid atrial rhythm. Atrial flutterĪn atrial flutter typically occurs in the right atrium, one of your heart’s two upper chambers. It’s the most common arrhythmia.Ītrial fibrillation, or AFib, occurs when many unstable electrical impulses misfire, causing your atria to quiver erratically.ĪFib causes your heart to beat irregularly and can increase your heart rate to 80 to 180 bpm, which is much faster than the typical 60 to 100 bpm. This disorganized heart rhythm occurs in the upper chambers of your heart. Ventricular tachycardia: Ventricular tachycardia is a very fast heart rate that occurs in the lower chambers, known as the ventricles.Supraventricular tachycardia: Supraventricular tachycardia originates in the upper chambers of your heart, known as the atria.With sinus tachycardia, your heartbeat returns to its usual rate once you get better or become calm. Sinus tachycardia: This is an increased heart rate that can occur in response to exercise, pain, dehydration, excitement, fever, or illness.Tachycardia is any resting heart rate over 100 beats per minute (bpm). For example, a typical heart beats 60 to 100 times per minute in adults. Tachycardia means that your heart is beating too fast. The most common types of abnormal heart rhythms include: Tachycardia
