Eye examination and corneal foreign body

…for signs of perforation — Seidel's sign, an irregular pupil, a soft globe — because a perforated eye must never be instrumented, have its pressure measured…

Sinus arrhythmia (respiratory sinus arrhythmia)

…the same phenomenon. Sinus arrhythmia fulfill all criteria for sinus rhythm except from the fact that the rhythm is slightly irregular ( Figure 1 ). This is…

Ambulatory blood pressure monitoring and Holter ECG

…are no absolute contraindications. Refrain or adapt in atrial fibrillation with a rapid and irregular ventricular rate (oscillometric measurement becomes unreliable), lymphoedema or a dialysis…

Leg ulcers — wound debridement and compression therapy

…heel, lateral malleolus, pressure points Beneath the metatarsal heads, toes, heel Edge Irregular, shallow Sharp, punched out Surrounded by callus Wound bed Fibrin covered, granulating…

🟠 QTc Interval Calculator (Bazett’s, Fridericia’s, Hodge's and Framingham Formulas)

…de pointes, a specific form of polymorphic ventricular tachycardia characterized by irregular (polymorphic) QRS complexes that appear to twist around the isoelectric baseline. The risk…

Adenosine for tachyarrhythmias (AVNRT, AVRT, NCT)

…Irregular wide complex tachycardia (absolute contraindication) . Irregular wide complex tachycardia is most often due to atrial fibrillation with wide QRS complexes due to bundle branch…

Assessment of Pacemaker Malfunction

…These failures typically result in missing stimulation artifacts, misplaced stimulation artifacts, irregular pacing, etc. Most cases of malfunction are associated with the electronics in the…

Premature atrial contraction (premature atrial beat / complex): ECG and clinical implications

…by the increased filling. Frequent premature beats can also be perceived as having an irregular heart rhythm (despite the underlying sinus rhythm). Although atrial premature…

Terminology of sudden cardiac arrest and resuscitation

…slow, irregular breaths with a frequency of 1 to 4 breaths per minute. Agonal breathing is frequently seen during the first minute after cardiac arrest…

Ventricular fibrillation, pulseless electrical activity and sudden cardiac arrest

…entry circuits , causing rapid and chaotic ventricular depolarizations, rendering the left ventricle incapable of generating effective contractions. This results in circulatory collapse, loss of consciousness…
