Symptoms of fast slow syndrome

summary

Tachycardia syndrome is a common type of sick sinus syndrome or sinus node dysfunction syndrome, which is characterized by paroxysmal tachyarrhythmia based on bradycardia. Bradycardia (sinus bradycardia, sinus atrial block or sinus quiescence) is generally significant. Tachyarrhythmias include atrial tachycardia, atrial fibrillation, supraventricular tachycardia, etc. atrial fibrillation is the most common, while ventricular tachycardia is rare. Sinus arrest often occurs when tachycardia is terminated. Symptoms of fast slow syndrome? Let's talk about it

Symptoms of fast slow syndrome

The manifestations are organ ischemia caused by bradycardia or tachycardia, such as dizziness, fatigue, palpitation, chest tightness, etc. Slow fast syndrome usually occurs in the elderly with underlying heart disease. The evidence of sinus bradycardia, sinus arrest or conduction block can be found in ECG.

After the sudden termination of tachyarrhythmia (mainly atrial fibrillation), a long interval (i.e. sinus arrest) occurs before the recovery of normal heartbeat. At this time, the patient will have chest tightness, dizziness, dizziness, transient blackness in front of eyes, and even syncope.

Tachyarrhythmia (atrial fibrillation, atrial flutter or atrial tachycardia) in fast slow syndrome occurs on the basis of normal heartbeat, while sinus arrest after tachyarrhythmia is mainly caused by transient inhibition of sinus node function. Fast slow syndrome usually occurs in relatively young patients, most of them have no organic heart disease, ECG is normal, and there is no evidence of sinus arrest or conduction block.

matters needing attention

Slow fast syndrome is caused by "slow", so we should first correct "slow" in treatment, permanent pacemaker implantation is the key to ensure heart rate; For tachyarrhythmia, antiarrhythmic drugs can be given. If drug treatment is ineffective, catheter radiofrequency ablation can be performed on the basis of pacemaker implantation
