Pulmonary oedema is a common cause of acute respiratory distress in critical care environments. Cardiogenic pulmonary oedema occurs when raised left ventricular filling pressure leads to raised left atrial pressure, raised pulmonary venous pressures and then elevated pulmonary capillary pressure.The Q Wave. A Q wave is any negative deflection that precedes an R wave. The Q wave represents the normal left-to-right depolarisation of the interventricular septum. Small ‘septal’ Q waves are typically seen in the left-sided leads (I, aVL, V5 and V6)The delay between activation of the RV and LV produces the characteristic “M-shaped” R wave seen in lateral leads. Delayed overall conduction time to the LV extends the QRS duration to ≥ 120 ms.

It can be caused by various conditions, such as heart disease, pulmonary embolus, or chest pain. …Other paper speeds: 50mm/sec. Doubling the standard rate will cause the ECG to appear drawn out or wider complex than 25mm/sec paper speeds. 1mm ( small square) = 0.02 sec (20ms) 5mm ( large square) = 0.1 sec (100ms) The rhythm strip will thus comprise 5 seconds total capture compared to the standard 10 seconds.„Erfolg ist kontinuierliches Wachstum.

Pleural effusion is most easily examined if a patient can sit up.The Delta wave is a slurred upstroke in the QRS complex. It relates to pre-excitation of the ventricles, and therefore often causes an associated shortening of the PR interval. It is most commonly associated with pre-excitation syndromes such as WPW.

Lead I: inversion of all complexes, aka ‘global negativity’ (inverted P wave, negative QRS, inverted T wave) Absent R-wave progression in the chest leads (dominant S waves throughout) These changes can be reversed by placing the precordial leads in a mirror-image position on the right side of the chest and ...The QT interval is the time from the start of the Q wave to the end of the T wave on an ECG. It represents the period of ventricular depolarisation and repolarisation. It is inversely proportional to heart rate and can be measured in different leads. It is used to diagnose and monitor arrhythmias, drugs, and conditions that affect the heart....

This causes a delayed/slurred initial QRS component. SVT with aberrancy displays initial sharp QRS deflections that arise from the preserved bundle branch. In VT, time to peak of depolarisation is often delayed at > 40ms in V1 or V2.Ultrasound Modules: Anatomical. Airway ultrasound Anatomy. Cardiac ultrasound and echocardiography.

The most important life-threatening causes of QRS widening are: Hyperkalaemia. Tricyclic antidepressant poisoning.The ST segment is the flat, isoelectric section of the ECG between the end of the S wave (the J point) and the beginning of the T wave. The ST Segment represents the interval between ventricular depolarization and repolarization.

Home Ultrasound Library. Empyema is a purulent pleural effusion. Seeding of the pleural space by bacteria or rarely fungi is usually from extension from adjacent pulmonary infection. Occasionally haematogenous or lymphatic spread occurs. Iatrogenic inoculation can also introduce infection. How long path reverberation artefact is formed (A-lines) The ultrasound beam hits the highly reflective pleural surface and is reflected back to the transducer. The first return results in a true image of the pleural surface on the monitor. The beam however reflects back again off the transducer face and the cycle repeats.Example 1. Marked first degree heart block. PR interval > 300 ms, P waves are buried in the preceding T wave. Example 2. Sinus bradycardia with 1st degree AV block. PR interval > 300 ms. Example 3.

Hypokalaemia is defined as a serum potassium level of < 3.5 mmol/L. ECG changes generally do not manifest until there is a moderate degree of hypokalaemia (2.5-2.9 mmol/L).

Pericardial tamponade is more common in penetrating thoracic trauma than blunt trauma. As little as 75 mL of blood accumulating in the pericardial space acutely can impair cardiac filling, resulting in tamponade and obstructive shock.
