  • New ECG markers for predicting long-term mortality and morbidity in patients receiving cardiac resynchronization therapy.
    by  Kisiel, Fijorek, Moskal, Kukla, Sondej, Czarnecka, and Jastrzębski
    • Highlights: The team investigated the prognostic value of four recently proposed ECG markers in patients with cardiac resynchronization therapy (CRT): 1. pathological preimplantation QRS axis, 2. increase in QRS amplitude in V3 during biventricular pacing, 3. negative QRS in V1/V2 during left ventricular (LV)-only pacing, and 4. longer QRS duration during LV-only pacing on 552 subjects.  Long LV-paced QRS and pathological axis predicted unfavorable prognosis in Kaplan-Meier analysis. In multivariable Cox model (functional class, LV ejection fraction, LV end-diastolic dimension, permanent atrial fibrillation, age, gender, heart failure etiology, creatinine level, diabetes mellitus), LV-paced QRS duration remained a significant determinant of both endpoints. The other studied ECG markers lacked independent prognostic value.

  • Outcome of all-comers with STEMI based on the grade of ischemia in the presenting ECG. 
    by  Koivula,  Eskola, Viikilä, Lilleberg, Huhtala,  Birnbaum, and Nikus. 
    • Highlights: The aim of the study was to establish the prognostic significance of grade 2 ischemia (G2I), G3I and the STEMI patients excluded from ischemia grading (No grade of ischemia, NG) in a real-life patient population. We assessed in-hospital, 30-day and 1-year mortality as well as other endpoints.  The NG patients had more comorbidities and longer treatment delays than the two other groups. Short-term and 1-year mortality were highest in patients with NG and lowest in patients with G2I. Maximum troponin level was highest in G3I, followed by NG and G2I. In logistic regression multivariable analysis, NG was independently associated with 1-year mortality.

  • New formula for defining “normal” and “prolonged” QT in patients with bundle branch block.
    by Yankelson, Hochstadt,  Sadeh,  Pick,  Finkelstein,  Rosso, and Sami Viskin.
    • Highlights:  The object of the study was to predict the QT interval in the presence of normal QRS for patients with left bundle branch block (LBBB). We measured the QT interval in patients with new onset LBBB who had a recent electrocardiogram with narrow QRS for comparison. 48 patients who developed in-hospital LBBB were studied. Patients who had similar heart rate before and after LBBB were included. We used linear regression, the Bogossian method, and our new fixed QRS replacement method to evaluate the most reliable correction method.

  • Noninvasive clues for diagnosing ventricular tachycardia mechanism
    by Andres Enriquez, MD, Michael Riley, MD, and Francis Marchlinski, MD.
    • Highlights:  The electrophysiologic mechanism of ventricular tachycardia (VT) are enhanced automaticity, triggered activity and reentry. Understanding the VT mechanism is relevant for the prognosis, pharmacological therapy and ablation strategy. We review clues from the history, 12-lead ECG, monitoring and response to pharmacologic agents, to predict the VT mechanism.

  • Smartphone ECG for evaluation of ST-segment elevation myocardial infarction (STEMI): Design of the ST LEUIS International Multicenter Study 
    by Alejandro Barbagelata, MD, Charles F. Bethea, MD, Harry W. Severance, MD, Robert J. Mentz, MD, David Albert, MD, Gregory W. Barsness, MD, Viet T. Le, PA-C, Jeffrey L. Anderson, MD, T. Jared Bunch, MD, Frank Yanowitz, MD, Benjamin Chisum, BS, Brianna S. Ronnow, MS, Joseph B. Muhlestein, MD.
    • Highlights:  In STEMI patients, a 12-lead ECG is vital for rapid diagnosis and immediate access to treatment.  New technology allows for 12-lead ECG readings through a smartphone app and attachment. ST LEUIS was designed to determine if the smartphone ECG is comparable to a standard 12-lead ECG.

  • Interatrial block, frailty, and prognosis in elderly patients with myocardial infarction. 
    by Eva Bernal, MD, Antoni Bayés-Genís, MD, PhD, Albert Ariza-Solé, MD, PhD, Francesc Formiga, MD, PhD, Maria T. Vidán, MD, PhD, Luis Alberto Escobar-Robledo, MS, Jaime Aboal, MD, Lídia Alcoberro, MD, Carme Guerrero, MD, Iván Ariza-Segovia, MD, Ana Hernández de Benito, MD, Pau Vilardell, MD, José Carlos Sánchez-Salado, MD, Victoria Lorente, MD, Antoni Bayés de Luna, MD, PhD, and Manuel Martinez-Sellés, MD, PhD
    • Highlights: Almost one of each three elderly patients with myocardial infarction in sinus rythm do not have a normal P wave on ECG.  Advanced interatrial block was associated with a trend toward more fraity, but not with the rest of geriatric syndromes. Elderly patients with MI and advanced IAB had a slightly higher mortality and new onset atrial fibrillation at one year.

  • Electrocardiographic recognition of right ventricular hypertrophy 
    by Kjell Nikus, MD, PhD, Andrés Ricardo Pérez-Riera, MD, PhDlink, Kaari Konttila, MS, and Raimundo Barbosa-Barros, MD.
    • Highlights: The ECG is a relatively insensitive tool for the detection of right ventricular hypertrophy, but some criteria have high specificity. ECG criteria are not sensitive/specific enough for screening for mild right ventricular hypertrophy in adults without clinical cardiovascular disease. The greatest accuracy of the ECG is in congenital heart disease
