Questão Responda
Image: Premature Atrial Contractions (binary/octet-stream)
Premature Atrial Contraction (Supra-ventricular Premature Contraction) ECG 1. Premature beat appears early 2. After this there is a compensatory pause before the next sinus p wave 3. This means that there is a really short RR interval and the very next RR interval is longer but is u combine these 2 their length will be shorter than 2 normal RR intervals due to the incomplete compensatory pause
Image: Supraventricular Tachycardia (binary/octet-stream)
Supraventricular Tachycardia ECG No p wave Very short RR interval Normal QRS
Image: Atrial Fibrilllation (binary/octet-stream)
Atrial Fibrillation ECG No P waves Arrhythmia F waves No isoelectric line
Image: Atrial Flutter (binary/octet-stream)
Atrial Flutter ECG F waves- sawtooth No p waves No isoelectric line
Image: Premature Ventricular Contractions (binary/octet-stream)
Premature Ventricular Contractions (Ventricular Extrasystole) ECG No P wave preceeding PVC Wide & Bizzare QRS. QRS will be at least 0.12s-0.14s
Image: Ventricular Tachycardia (binary/octet-stream)
Ventricular Tachycardia ECG Monomorphic QRS complex- all look the same- from re-entrant loop Polymorphic QRS Increased heart rate Regular rhythm No p-wave or disassociated p-wave No PR interval Wide QRS width
Image: Ventricular Fibrillation (binary/octet-stream)
Ventricular Fibrillation ECG Chaotic rhythm No p wave No PR interval No QRS complex is identifiable Looks like a bunch of squiggly line
Image: First Degree Av Block (binary/octet-stream)
AV Block Type 1 ECG The signal to AV node is delayed Increased PR Interval
Image: Av Block Type 2 Mobitz 1 (binary/octet-stream)
AV Block Type 2a (Mobitz 1) ECG The signal (PR interval) gets progressively delayed until a ‘dropped beat’
Image: Av Block Type 2 Mobitz 2 (binary/octet-stream)
AV Block Type 2b (Mobitz 2) ECG There are intermittent random dropped beats No PR lengthening
Image: Av Block Type 3 (binary/octet-stream)
AV Block Type 3 (Complete) ECG P waves have no relation to QRS intervals
Image: Right Bundle Braanch Block (binary/octet-stream)
Right Bundle Branch Block ECG 1. Shows RR waves due to slow activation of contraction left/right ventricles • ‘Bunny ears’ 2. Wide QRS Complex 3. RR wave in right leads- V1 and V2 4. S wave in Lead 1 is wider >0.04 and this S wave is also in V5 and V6
Image: Left Bundle Branch Block (binary/octet-stream)
Left Bundle Branch Block ECG 1. Shows RR waves due to slow activation of contraction left/right ventricles • ‘Bunny ears’ 2. Wide QRS complex 3. RR wave in left leads- V5 and V6 4. Also RR in first and aVL 5. R wave don’t increase in V1 to V4- Pathological progression
Image: Sa+Node+Block (binary/octet-stream)
SA Node Block Heart Rate- Varies Rhythm- Irregular P waves- Present and normal Pr Interval- Normal Dropped Beats- present
Image: Wpw (binary/octet-stream)
Wolf Parkinson White Syndrome Short PR interval “Delta wave“ - A delta wave is slurring of the upstroke of the QRS complex. Short PR interval Wider QRS complexes
