Introduction:
EP Mobile is an essential, free medical reference application designed specifically for healthcare professionals managing cardiac arrhythmias. This digital toolkit consolidates a vast array of critical calculators, risk scores, and diagnostic algorithms into a single, mobile resource. For cardiologists, electrophysiologists, fellows, and nurses, EP Mobile streamlines complex calculations at the point of care, enhancing diagnostic accuracy and supporting clinical decision-making. Its comprehensive nature makes it an indispensable asset for anyone working in cardiology, electrophysiology, or emergency medicine.
Advanced Arrhythmia Risk Stratification Tools
EP Mobile provides immediate access to numerous validated risk scores. A user simply selects the desired calculator, such as the CHA₂DS₂-VASc for stroke risk in atrial fibrillation or the HAS-BLED for bleeding risk. They then input the patient's relevant clinical parameters into the provided fields. EP Mobile instantly computes the score, presenting the result clearly. This allows for rapid, evidence-based assessment during patient consultations, helping to guide treatment plans for anticoagulation or device therapy without manual calculation errors.
Precise Drug Dosing and Reference Guides
This function within EP Mobile assists with medication management for arrhythmias. Users navigate to the drug calculators for medications like dofetilide or sotalol. They enter patient-specific data, including renal function via creatinine clearance, which EP Mobile can also calculate. The app then provides the appropriate, adjusted medication dose based on the latest guidelines. This feature ensures safe prescribing practices, helps avoid toxicity, and supports pharmacy reconciliation processes directly from a clinician's mobile device.
Complex ECG and Electrophysiology Algorithm Support
EP Mobile demystifies complex ECG interpretations and EP study findings. For a wide-complex tachycardia, a clinician can run through the integrated Brugada algorithm, inputting ECG observations step-by-step to aid diagnosis. For Wolff-Parkinson-White (WPW) syndrome, users can apply different accessory pathway localization algorithms (Arruda, Milstein) by entering ECG lead data. EP Mobile processes this to suggest a likely anatomical location, providing valuable pre-procedural planning insights for ablation cases.
Diagnostic Criteria for Inherited Cardiomyopathies
The application serves as a quick reference for diagnosing complex inherited conditions. A user suspecting ARVC (Arrhythmogenic Right Ventricular Cardiomyopathy) can pull up the 2010 Task Force Criteria within EP Mobile. They can systematically check off the patient’s imaging, histopathological, ECG, and arrhythmic findings. EP Mobile tallies the results to confirm if diagnostic thresholds are met. This organized approach ensures no major criterion is overlooked during the diagnostic workup.
Practical Clinical Calculators and Utilities
Beyond specialized algorithms, EP Mobile includes essential daily utilities. Clinicians frequently use the QTc calculator, choosing from multiple formulas (Bazett, Fridericia) and inputting the heart rate and measured QT interval. The app corrects and displays the QTc value. Other tools, like the interval-to-rate converter or body weight calculators, offer quick answers to common questions during rounds or in the EP lab, saving time and improving workflow efficiency.
