Ictal Bradycardia

Ictal Bradycardia is a medical condition characterized by a significant decrease in heart rate that occurs during or after a seizure. This condition is a subtype of ictal cardiac dysrhythmias, which are abnormal heart rhythms associated with seizures.

Etiology[edit | edit source]

The exact cause of ictal bradycardia is not fully understood. However, it is believed to be related to the activation of the parasympathetic nervous system during seizures, which can slow the heart rate. Other factors that may contribute to ictal bradycardia include the type and location of the seizure, underlying heart conditions, and certain medications.

Clinical Presentation[edit | edit source]

Patients with ictal bradycardia may experience symptoms such as dizziness, fainting, shortness of breath, and chest pain. In severe cases, ictal bradycardia can lead to cardiac arrest and sudden death.

Diagnosis[edit | edit source]

Diagnosis of ictal bradycardia typically involves a combination of electrocardiogram (ECG) monitoring and video EEG monitoring during a seizure. Other diagnostic tests may include Holter monitor and event monitor.

Treatment[edit | edit source]

Treatment for ictal bradycardia primarily involves managing the underlying seizure disorder. This may include medications, vagus nerve stimulation, or surgery. In some cases, a pacemaker may be implanted to regulate the heart rate.

Prognosis[edit | edit source]

The prognosis for individuals with ictal bradycardia varies depending on the severity of the condition and the effectiveness of treatment. With appropriate management, many individuals can lead normal lives.
