The most dangerous arrhythmia is ventricular fibrillation, in which your ventricles quiver rather than beat steadily in time with your atria. The more lethal types of arrhythmia tend to be those that originate in your ventricles. Similar to atrial fibrillation, atrial flutter involves a rapid heartbeat, but those beats are somewhat more organized and less erratic. The primary treatment for atrial fibrillation is taking a blood thinner to prevent blood clot formation and a medication to slow your heart rate when it’s in arrhythmia. If your heartbeat is very fast, this can become a life threatening emergency.Ītrial fibrillation is an arrhythmia that occurs when your atria quiver or beat in a chaotic manner. In these cases, no treatment may be necessary.īut if episodes are lengthy, frequent, or lead to other symptoms, then some therapy may be recommended. These episodes are often short and may cause no other symptoms. Supraventricular tachycardia is characterized by episodes in which your heart beats faster than expected. While all types of arrhythmias are potentially dangerous, there are some that are less likely to become life threatening. There are several types of atypical heart rhythms within each of these categories. Most arrhythmias are also classified as either tachycardia (atypically fast rhythm) or bradycardia (atypically slow rhythm). Ventricular arrhythmias originate in your ventricles, while supraventricular arrhythmias start above your ventricles.

There are two main types of arrhythmias: ventricular and supraventricular. Someone in cardiac arrest will be unconscious and unresponsive, and they may gasp for breath. In cases of life threatening arrhythmias, sudden cardiac arrest may occur. More severe and possible lethal arrhythmias often have more serious symptoms, including:

sensation that your heart “skips” a beat.

But signs of the condition can include one or more of the following: Symptoms may vary, depending on the type of arrhythmia affecting your heart.

left bundle branch, which carries electrical signals to the left ventricle.

right bundle branch, which carries electrical signals to the right ventricle.

atrioventricular node, which sends impulses to the ventricles, causing them to contract and pump blood out of your heart.

sinoatrial node, which sends electrical impulses to the atria, causing them to contract and move blood down to the ventricles.

ventricles, which pump blood out of your heart.

atria, which receive blood from your veins.

The ventricles and atria work in a synchronized fashion to receive blood from the rest of your body, move it into your lungs for oxygen, and then pump it back out to the rest of your body.īut the electrical system that controls your heart rate can sometimes stop working properly, resulting in arrhythmia.Īrrhythmia can originate in different parts of your heart, such as the: This prompted researchers to advise clinicians to be aware of the association between arrhythmia and COVID-19 when treating new patients.Ī healthy heart beats about 100,000 times per day.

problems with bladder or bowel functionĪ 2020 study suggests that the risk of arrhythmia among individuals with COVID-19 is heightened because of “systemic illness” brought on by the infection, rather than as a direct threat to heart function.Ī separate study found that among the people with serious COVID-19 infections, about 44 percent had arrhythmia.

low blood pressure when standing ( orthostatic hypotension).

In addition to an irregular heartbeat, people with long-haul COVID-19 who experience dysautonomia may have other symptoms: While dysautonomia can be dangerous, it’s usually not serious when associated with COVID-19. The most common arrhythmia seen in people with long-term COVID-19 is related to an autonomic nervous system condition called dysautonomia.

This heart condition is a common lingering effect in people who experience COVID-19 symptoms for months after the infection has apparently cleared their body. Although COVID-19 is still largely considered a disease of your respiratory system, there is clear evidence that the infection can cause cardiac complications, including arrhythmia.
