Summary
Invasive electrophysiological studies in 127 patients revealed conduction disturbances in the cardiac conduction system. Multifocal affection, diagnosed in 45% of cases, supports the term "disease of cardiac conduction system".
Area of Science:
- Cardiology
- Electrophysiology
- Pathology
Background:
- Cardiac conduction system disturbances can arise from various pathological findings.
- Electrophysiological invasive examination is a key diagnostic tool for assessing these disturbances.
- Understanding the localization of conduction issues is crucial for diagnosis and treatment.
Purpose of the Study:
- To evaluate the localization of conduction disturbances within the cardiac conduction system.
- To determine the prevalence of single versus multifocal affections.
- To provide recommendations for terminology based on findings.
Main Methods:
- Electrophysiological invasive examination was performed on 127 patients.
- Patients with pathological findings in the cardiac conduction system were analyzed.
- Localization of conduction disturbances was assessed.
Main Results:
- A total of 127 patients with pathological cardiac conduction system findings were evaluated.
- Single focus of conduction disturbance was observed in 70 patients.
- Multifocal affection was identified in 57 patients (45%).
Conclusions:
- The study confirms findings consistent with existing literature on cardiac conduction system diseases.
- A multifocal disturbance of the conduction system was observed in a significant portion of patients (45%).
- The term "disease of cardiac conduction system" is recommended for cases with multifocal conduction disturbances.
