40 Possible Causes for Abnormal Pulse, P Wave Absent

  • Ventricular Fibrillation

    Answers Rhythm: Irregular Rate: Unable to determine P Wave: absent PR interval: absent QRS: absent Interpretation: Ventricular Fibrillation (Fine) Description The morphologic[] Ventricular fibrillation disrupts the synchrony between the heartbeat and the pulse beat.[] Ventricular fibrillation is an abnormally irregular heart rhythm caused by rapid, ineffective, uncoordinated contraction of the ventricles which produce no peripheral pulse[]

  • Atrial Fibrillation

    P waves are absent and replaced by irregular electrical activity. The ventricular rate is irregular and chaotic.[] There is an initiative called "Check Your Pulse" aimed at identifying abnormal heart rates and patients with undiagnosed atrial fibrillation early.[] P waves are absent and replaced by irregular electrical activity. The ventricular rate is irregular and chaotic. Figure 1 Electrocardiogram showing atrial fibrillation.[]

  • Atrial Standstill

    Diagnostic criteria of atrial standstill Absent P waves both on surface and intracardiac ECG. Junctional bradycardia.[] […] ventriculography have described a spectrum of left ventricular filling abnormalities that appear to be related to disease progression and severity. 6 , 7 In the early stages[] EKG Absent P waves. JVP Absent A waves.[]

  • Sinus Arrest

    Occasionally and when the P waves are absent for a relatively long time, escape beats appear, as other groups of myocardial cells undertake the pacemaking process for a brief[] Symptoms of SSS include: fainting or fainting sensations fatigue dizziness palpitations (abnormal heart beats) very slow pulse (bradycardia) difficulty breathing chest pain[] waves: Sinus P waves with basic rhythm; absent during pause PR interval: Normal (0.12 to 0.20 second) with basic rhythm; absent during pause QRS complex: Normal (0.10 second[]

  • Hyperkalemia

    Role of inducing K loss via the GI tract in the management of hyperkalemia Setting Recommendations Hyperkalemia with severe ECG changes (e.g. absent P waves, wide QRS complex[] It may cause abnormal heartbeats, irregular pulse and nausea. Hyperkalemia may result from alcoholism kidney disease and Addison’s disease.[] Other clinical signs include muscular weakness and a slow irregular pulse.[]

  • Atrial Flutter

    Nonetheless, the pulse rate often is abnormally high (a normal pulse for an individual at rest is about 60 to 80 beats per minute) and most patients will experience some symptoms[] But if your pulse continues to be irregular, it can be a sign of atrial fibrillation – an irregular and often abnormally fast heart rate.[] It moves in an organized abnormal circular motion, or "circuit," causing the atria to beat faster than the ventricles of your heart.[]

  • Atrioventricular Junctional Rhythm

    P waves may be present or absent. P waves may not be related to the QRS complexes.[] […] femoral pulse Abnormal pulse rate Abnormal radial pulse Accelerated idioventricular rhythm Anadicrotic pulse Apex beat displaced - LVH Apex beat displaced - RVH Atrial bigeminy[] How to Identify a Junctional Rhythm A junctional rhythm can be identified by having a regular R-R interval and one of the following P wave characteristics: Absent P Waves:[]

  • Sinoatrial Block

    There is progressive shortening of the P-P interval, followed by an absent P wave-QRS complex.[] Severe bradycardia or other rhythm abnormalities, weak arterial pulses and hypotension can be observed during cardiac auscultation.[] In 3rd-degree SA block, conduction is blocked; P waves are absent, giving the appearance of sinus arrest.[]

  • Ventricular Tachycardia

    Answers Rhythm: Regular Rate: 150 P Wave: absent PR interval: n/a QRS: Wide and bizarre Interpretation: Ventricular Tachycardia[] In ventricular tachycardia, abnormal electrical pulses in the lower chambers, or ventricles, disrupt the normal firing of the SA node, causing the heart to beat rapidly.[] Rhythm Regular Rate Fast (100-250 bpm) P Wave Absent PR Interval Not measurable QRS Wide ( 0.10 sec), bizarre appearance Notes[]

  • Atrial Tachyarrhythmia with Short PR Interval

    Rhythm Irregular Rate Very fast ( 350 bpm) for Atrial, but ventricular rate may be slow, normal or fast P Wave Absent - erratic waves are present PR Interval Absent QRS Normal[] Examination There is usually no abnormality to be found between attacks, although some people have a resting sinus tachycardia.[] P waves are either absent or abnormal (e.g. inverted) with a short PR interval ( retrograde P waves).[]
