ECG Report - Safiya, Female, 53 Years | 31-05-2026, 06:48 PM

Machine-Reported Parameters

Rhythm

• Sinus rhythm at 92 bpm - normal rate, slightly toward the upper end of normal
• P waves are upright in I and II, inverted in aVR - confirming normal sinus origin
• Regular R-R intervals
• PR interval 120 ms - normal (lower limit of normal; not pre-excitation as delta waves are absent)

Conduction

• QRS duration 84 ms - narrow, no bundle branch block
• PR 120 ms - short-normal; no overt Wolff-Parkinson-White pattern on visual inspection
• No pathological Q waves identifiable

QT Interval

• QTc 428 ms - within normal limits for a female (upper limit ~460 ms per AHA/ACC)
• No significant QT prolongation

Axis

• P axis: +19° - normal
• QRS axis: -16° - borderline left axis deviation (LAD). Mild, within the -0° to -30° range; could represent normal variant or early LAFB. Warrants correlation with clinical context.
• T axis: +51° - normal

ST Segments & T Waves

• No obvious ST elevation or depression on visual review
• T waves appear concordant with QRS in most leads
• Machine diagnosis confirms "Normal ECG"

Voltage

• RV5 0.887 mV, SV1 0.892 mV - RV5 + SV1 = ~1.78 mV, which is below the Sokolow-Lyon threshold of 3.5 mV - no voltage criteria for LVH

Notable Points for the Cardiologist

1. Borderline QRS axis (-16°): Mild leftward shift. In isolation this is often a normal variant, but in a 53-year-old female consider correlation with history of hypertension, coronary artery disease, or early left anterior fascicular block (LAFB). LAFB classically shows axis between -45° and -90° with rS in II, III, aVF and qR in I, aVL - this tracing does not meet full LAFB criteria.
2. QTc 428 ms: Normal but should be monitored if the patient is prescribed QT-prolonging drugs (antiarrhythmics, antihistamines, fluoroquinolones, antipsychotics), especially relevant in female sex (inherently longer QTc baseline).
3. Rate 92 bpm: Mild sinus tachycardia territory. Evaluate for pain, anxiety, anemia, fever, thyroid disease, or dehydration as contributing factors.
4. PR 120 ms: Low-normal; no delta waves, no short PR with accessory pathway physiology evident.
5. Machine reads "Normal ECG" - the automated Glasgow algorithm (V28.6.0) confirms normality, consistent with visual interpretation.
