LAVADENZ MORALES, Roberto. CORRELATION OF CARDIAC ARRHYTHMIAS WITH SYMPTOMS FOR THE 24 HOURS HOLTER. Rev. Méd. La Paz [online]. 2013, vol.19, n.2, pp.28-36. ISSN 1726-8958.

Introduction.- The 24 hours Holter monitoring is used as an exam noninvasive, to detect cardiac arrhythmias and to correlate with the symptoms that the patient refers. Objetives.- To correlate the arrhythmia and the symptom. To determinate: the capacity of the arrhythmia to cause symptoms, sensibility of the symptom to detect arrhythmias and treatment possibilities with the results. Methods.- Thousand hundred forty six studies were made, the patients took a diary, whey they wrote the symptoms, and the hour the same ones, pressing the button of the events of the recorder. It was defined: as positive correlation, when the arrhythmia coincided with the symptom, negative correlation, if the arrhythmia didn't coincide with the symptom, or the same one was absent; if they didn't register arrhythmias, it was qualified like uncertain study. The mean of the values were correlated, to obtain difference statistic and the index of sensibility and specificity were calculated. Results.- During the study 42% they had symptoms: palpitations 81%, presyncope 15%, dyspnoea 3%, chest pain 7%. In 82%, they were registered arrhythmias: Supraventricular premature beats 71%, Ventricular premature beats 68%, Supraventricular Tachycardia 17%, Atrial Fibrillation 8%, Sinus Tachycardia 7%, A-V Heart Block 4%, Ventricular Tachycardia 2%, Atrial Flutter 2%, Sinus Arrest 0,5%. Correlation positive was in 22%, being bigger for the palpitations in 58%, then the chest pain 26%, presyncope 25% and dyspnea 20%. The Sinus Tachycardia, the Sinus Arrest, and the Atrial Flutter, produced more symptoms, the premature beats, produced less symptoms. The sensibility of the symptom to detected arrhythmias, it was 43% and the specificity 66% . Normal studies were 18%. Conclusion.- There was a low correlation betwen symptoms and arrhythmias, as well as the sensibility of the symptom to detected arrhythmias. Should take in account the frecuency of the symptoms to indicate the study, being preferable to use the Cardiac Events recorders, when the symptoms are not daily.
