Smartphone Twelve Lead Electrocardiogram Utility In ST Elevation Myocardial Infarction

2019-08-20 20:17:12 | BioPortfolio


The primary objective is to determine if the Smartphone electrocardiogram (ECG) is an acceptable replacement for a standard ECG in the identification of ST elevation myocardial infarction (STEMI).


Toward this objective, this study involves the following:

- Obtain simultaneous recordings of a standard 12-lead ECG and the iPhone "12-lead equivalent" ECG on patients presenting with chest pain in which the STEMI protocol was activated.

- Obtain simultaneous recordings of a standard 12-lead ECG and the iPhone "12-lead equivalent" ECG on patients presenting to the Emergency Department for evaluation of chest pain, not necessarily presenting with STEMI.

- Reading of ECGs (standard 12-lead and iPhone) by three independent cardiologists, who are blinded to the initial clinical ECG readings, the type of ECG equipment used, and the patient's clinical information.

- Assess the operational feasibility of using the Smartphone to obtain "12-lead equivalent" ECG recordings in patients suspected to have STEMI, and

- Determine the possibility of pooling the data obtained from this study with data from other institutions conducting identical studies, and developing a future IRB-approved protocol and statistical analysis plan to compare the sensitivity, specificity, positive predictive value and the negative predictive power of the iPhone ECG, using a paired standard 12-lead ECG as the gold standard.

There will be no therapeutic interventions. A single research-related procedure will be required, i.e. an iPhone ECG. Effort will be made to ensure that the performance of this procedure will not delay any treatment and/or diagnostic procedures that are part of usual or specialized care that the patient requires. Effort will be made to enroll 1 STEMI patient for every 2 non-STEMI patients.

Medical and Biotech [MESH] Definitions

A myocardial infarction that does not produce elevations in the ST segments of the ELECTROCARDIOGRAM. ST segment elevation of the ECG is often used in determining the treatment protocol (see also ST Elevation Myocardial Infarction).

MYOCARDIAL INFARCTION in which the anterior wall of the heart is involved. Anterior wall myocardial infarction is often caused by occlusion of the left anterior descending coronary artery. It can be categorized as anteroseptal or anterolateral wall myocardial infarction.

A clinical syndrome defined by MYOCARDIAL ISCHEMIA symptoms; persistent elevation in the ST segments of the ELECTROCARDIOGRAM; and release of BIOMARKERS of myocardial NECROSIS (e.g., elevated TROPONIN levels). ST segment elevation in the ECG is often used in determining the treatment protocol (see also NON-ST ELEVATION MYOCARDIAL INFARCTION).

Disease-related laceration or tearing of tissues of the heart, including the free-wall MYOCARDIUM; HEART SEPTUM; PAPILLARY MUSCLES; CHORDAE TENDINEAE; and any of the HEART VALVES. Pathological rupture usually results from myocardial infarction (HEART RUPTURE, POST-INFARCTION).

MYOCARDIAL INFARCTION in which the inferior wall of the heart is involved. It is often caused by occlusion of the right coronary artery.
