EP Mobile

EP Mobile is a comprehensive medical reference application designed specifically for cardiac electrophysiology and arrhythmia management. This powerful tool assists cardiologists, fellows, and other healthcare professionals by providing instant access to critical risk scores, diagnostic algorithms, and drug calculators at the point of care. Its primary value lies in consolidating complex, time-sensitive clinical data into a portable format, enabling quicker, more informed decision-making. The utility of EP Mobile makes it an indispensable digital aid for any medical professional dealing with heart rhythm disorders.

Arrhythmia Risk Score Calculations

Users begin by selecting a specific risk score, such as CHA₂DS₂-VASc for stroke risk in atrial fibrillation, from EP Mobilelication's organized menu. The interface then presents a series of input fields corresponding to the clinical parameters of the chosen algorithm, like age, history of hypertension, or prior stroke. After entering the patient's data, the user taps the calculate button. EP Mobile instantly processes the inputs and displays the final risk score, often accompanied by a brief interpretation. This allows for rapid patient assessment during consultations or hospital rounds, directly influencing treatment plans.

Diagnostic Algorithm Implementation

This function enables clinicians to systematically narrow down a diagnosis for complex conditions like wide-complex tachycardias. The user works through a step-by-step flowchart, answering yes or no to specific ECG criteria questions presented by EP Mobile, such as the presence of an RS complex in certain leads. Based on the responses, EP Mobile logic eliminates possibilities and guides the user toward the most probable diagnosis, such as VT versus SVT with aberrancy. This structured approach helps standardize the interpretation of challenging ECGs and reduces diagnostic uncertainty in urgent situations.

Drug Dosing and Interaction Guidance

Healthcare providers use this section to determine precise medication dosages, particularly for anticoagulants with complex dosing regimens like apixaban or dofetilide. The user first selects the specific drug calculator, then inputs required patient metrics such as creatinine clearance, age, and weight. EP Mobile computes the recommended dose and frequency based on evidence-based protocols. For drugs like warfarin, EP Mobile can also calculate a weekly dosing schedule. This feature mitigates the risk of manual calculation errors and ensures dosing is appropriately adjusted for renal function and other key factors.

ECG Criteria and Calculator Tools

This suite of tools assists in the quantitative analysis of electrocardiograms. A user can calculate a corrected QT interval (QTc) by manually entering the measured QT and RR intervals and then selecting from various formulas like Bazett or Fridericia. EP Mobile performs the calculation and indicates if the result is within a normal range or prolonged. Similarly, users can input voltage measurements to check for left ventricular hypertrophy using various criteria. These calculators provide immediate, objective data to support ECG interpretations and documentation.

Procedural Reference and Techniques

This component serves as a quick refresher for electrophysiology lab procedures and techniques. A clinician preparing for a case might navigate to the entrainment mapping section within EP Mobile to review the fundamental concepts and equations used to differentiate a reentrant circuit from a focal tachycardia. EP Mobile provides concise explanations and formulas, such as the post-pacing interval minus the tachycardia cycle length. This on-the-spot access to procedural theory aids in both planning and real-time execution of complex electrophysiology studies.
