Introduction: Sleep apnoea-hypopnoea syndrome has been associated to heart rate alterations; however, in our fields there is few data of the clinical characteristics and heart rate disorders in individuals with this syndrome who have been subject to 24-hours ECG Holter monitoring. Methods: This is a case series descriptive study, with data collection of clinical records including age, gender, medical history, echocardiogram, polysomnography results and ECG Holter monitoring diagnosis in patients with obstructive sleep apnoea hypopnoea syndrome at a third level centre. Results: 149 registers were analysed, with an average age of 63.01 (SD: 11.76); 101 patients (67.8%) showed some kind of heart rate disorder and 86 (57.7%) some type of arrhythmia. Being female and suffering from obstructive pulmonary disease were related to the presence of heart arrhythmia (p < 0.05). Conclusion: In this study the presence of heart arrhythmias in patients with obstructive sleep apnoea hypopnoea syndrome subject to 24-hour ECG Holter monitoring was of 57.7%; the most common disorder were ventricular extrasystoles, which accounted for 28.9%. Being female and suffering from obstructive pulmonary disease could be linked with an increase of heart rate disorders in patients with obstructive sleep apnoea hypopnoea syndrome. Analytical studies are required to corroborate the findings.
