ECG changes during cerebral angiography. An analysis of 334 patients--942 cerebral angiographies
Insights
Significant heart rate changes, including bradycardia and tachycardia, were observed during cerebral angiography. Young patients with subarachnoid hemorrhage and those with neoplastic disease showed specific heart rate responses.
Area of Science:
- Neurology
- Cardiology
- Radiology
Background:
- Cerebral angiography is a common diagnostic procedure.
- Heart rate (HR) changes can occur during medical interventions.
- Understanding these changes is crucial for patient safety.
Purpose of the Study:
- To analyze the incidence and characteristics of significant heart rate changes (>20%) during cerebral angiography.
- To identify patient factors associated with tachycardial and bradycardial effects.
Main Methods:
- Retrospective analysis of 942 cerebral angiographies from 334 patients.
- Categorization of HR changes into tachycardia and bradycardia.
- Statistical analysis to identify correlations with patient demographics and conditions.
Main Results:
- 14.9% of patients experienced tachycardia; 7.1% experienced bradycardia.
- Two patients (0.5%) had cardiac standstill, both without atropine after subarachnoid hemorrhage.
- Young, unpremedicated patients with subarachnoid hemorrhage showed high bradycardia incidence.
- Neoplastic disease patients with initial bradycardia showed high tachycardia incidence.
Conclusions:
- Heart rate fluctuations are notable during cerebral angiography.
- Specific patient populations (young, subarachnoid hemorrhage, neoplastic disease) exhibit distinct HR responses.
- Atropine premedication may be considered in specific high-risk patient groups.
Abstract:
We have analyzed HR changes greater than 20% among 334 patients and 942 cerebral angiographies. A tachycardial effect was seen in 14.9% of patients, while a bradycardial effect was seen in 7.1% including two patients having cardiac standstill (0.5%). These two patients were examined without atropine premedication after subarachnoid hemorrhage. Patients under 19 years of age, unpremedicated with atropine sulfate and suffering from subarachnoid hemorrhage secondary to ruptured aneurysm or arteriovenous malformation showed a significantly high incidence of bradycardia. On the other hand, patients with the neoplastic disease and having an initial sinus bradycardia showed a significantly high incidence of a tachycardial effect.
