“…1 In absolute numbers this amounts to up to several hundred thousand out of the 40 million ECGs recorded annually in the United States. 4 Cable misplacement can produce ECG abnormalities simulating ectopic rhythm, intraventricular conduction disturbance, 5,6 chamber enlargement or ventricular pre-excitation, 7 as well as simulating 6,[8][9][10][11] or concealing 12 myocardial ischaemia or infarction. Although the most common cable reversals, such as interchange of the right arm (RA) and left arm (LA) cables are usually detected even by inexperienced ECG readers or standard computer programs for ECG interpretation, less frequent cable misplacements may be less obvious and often remain unnoticed both by man and computer.…”

Incorrect electrode cable connection during electrocardiographic recording

Incorrect electrode cable connections during electrocardiographic (ECG) recording can simulate rhythm or conduction disturbance, myocardial ischaemia and infarction, as well as other clinically important abnormalities. When only precordial or only limb cables, excluding the neutral cable, have been interchanged the waveforms in the different leads are re-arranged, inverted, or unchanged, whereas the duration of intervals is not changed. The mistake can be recognized by the presence of unusual P-QRS patterns (e.g. negative P-QRS in lead I or II, positive in lead AVR, P-QRS complexes of opposite direction in leads I and V6, etc.), change in the P-QRS axis, or abnormal precordial QRS-T wave progression. Interchange of limb cables with the neutral cable distorts Wilson's terminal and the morphology of all precordial and unipolar limb leads. The telltale sign of the mistake is the presence of (almost) a flat line in lead I, II or III. Interchange of even one of the limb cables, except for the neutral cable, with a precordial cable distorts the morphology of most leads and leaves not more than one lead (I, II, or III) unchanged. Computerized algorithms for detection of lead misplacement, such as those based on artificial neural networks, or on correlation between original and reconstructed leads, have been developed.

“…In the interim, innovative teaching methods using computer-based instruction can be used to augment both formal and informal instruction. 7,46 Our study has several limitations. Not all of the clerkship directors at the 142 accredited allopathic medical schools or the 23 accredited colleges of osteopathic medicine in the U.S. and Canada are represented in CDIM.…”

Introduction The interpretation of the electrocardiogram (ECG) is fundamental for the identification of cardiovascular diseases, which are among the main causes of death in the world. The acquisition of this competence is essential in the training of the general practitioner and the use of new teaching tools, based on technology such as the use of mobile learning, can facilitate the acquisition of this knowledge. Objectives The objective of this study was to develop and evaluate the usability and the potentiality for the use in medical education of a mobile teaching application for ECG interpretation. Methods With the participation of two health professors and a computer scientist, a systems analyst, a programmer and a graphic designer, a mobile application was developed to teach ECG interpretation using the Java language. For validation analysis, a usability evaluation questionnaire based on the System Usability Scale (SUS) and a questionnaire used to evaluate the suitability of software for use in medical education, previously translated into Portuguese and applied in Brazil, were used. Results The “ECG Fácil” application was developed for off-line use and free access on iOS and Android platforms. In the validation phase of the application, a total of 109 students had free access to the mobile application for 6 weeks and then evaluated usability through a SUS-based questionnaire. The answers to the questionnaire showed good reliability, according to the validation analysis by Cronbach’s alpha coefficient (value: 0.74), and the application presented an excellent acceptance with a mean score on the SUS scale of 85.3. Meanwhile, fifteen faculty members evaluated the application through the questionnaire used to assess the suitability of software for use in medical education, with most agreeing with items indicating that it is suitable for use in medical education. Conclusion The “ECG Fácil” application was considered to be of good usability by students and suitable for educational purpose by teachers. Future studies with this application will be needed to assess the acquisition and retention of knowledge about ECG interpretation by students.
