Trifascicular block is a type of heart block that affects the electrical conduction system in the heart. This condition occurs when there is a disruption in the signals that travel from the upper chambers (atria) to the lower chambers (ventricles) of the heart. It is called trifascicular block because it affects all three of the heart's electrical pathways or fascicles.
Trifascicular block is relatively rare and affects less than 1% of the population. It is more common in older people and those with underlying heart conditions. Some of the causes of trifascicular block include:
Trifascicular block can cause a range of symptoms, including:
If you experience any of these symptoms, it is important to seek medical attention immediately. Your doctor may perform an electrocardiogram (ECG) to diagnose trifascicular block. They may also perform other tests, such as an echocardiogram or stress test, to assess the severity of the condition and identify any underlying causes.
Treatment for trifascicular block may include medication, such as beta-blockers or calcium channel blockers, to slow the heart rate and improve the heart's electrical conduction. In some cases, a pacemaker may be necessary to regulate the heart's rhythm. Your doctor will develop a treatment plan based on the severity of your condition and any underlying health issues.
Overall, trifascicular block is a serious condition that requires prompt diagnosis and treatment. If you have any concerns about your heart health or experience any symptoms, speak with your doctor as soon as possible.
