AF, supraventricular tachycardia (SVT runs of \u22655\u2009QRS), and other arrhythmias were assessed in the first 72\u2009h of Holter recording, in 7 day-recording, and in handheld ECG strips.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>72\u2009h-recording revealed AF in four cases (5.6%) and SVT in 18 (25%) cases. 7 day Holter confirmed AF in seven patients (10%) and SVT in 27 patients (37.5%).
