60 Possible Causes for P Wave Absent, Syncope

  • Sinus Arrest

    Abstract Cough syncope is a syndrome in which dizziness or syncope occurs after prolonged bouts of cough.[] 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[] 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[]

  • Ventricular Fibrillation

    […] study, we employed whole-exome sequencing in combination with arrhythmia-related gene filtering to identify the genetic lesion for a family suffering from suspicious IVF, syncope[] Answers Rhythm: Irregular Rate: Unable to determine P Wave: absent PR interval: absent QRS: absent Interpretation: Ventricular Fibrillation (Fine) Description The morphologic[] RESULTS: Frequencies of history of syncope and spontaneous type 1 ECG, r-J interval in V1, QRS duration in V6, and LAS40, Tpeak-Tend dispersion, and max T-wave alternans were[]

  • Atrial Fibrillation

    Disease prevalence is increasing at an alarming rate worldwide, and is associated with often catastrophic and costly consequences, including heart failure, syncope, dementia[] P waves are absent and replaced by irregular electrical activity. The ventricular rate is irregular and chaotic.[] . 1,2 Atrial fibrillation develops as a paroxysmal disorder characterized by rapid, irregular electrical activation of the atria and can be associated with palpitations, syncope[]

  • Atrial Flutter

    Abstract A 46-year-old man was admitted to our hospital for near syncope and palpitations.[] At hospital admission she reported no family history of sudden cardiac death, nor syncope or paroxysmal palpitations.[] Signs and Symptoms Diagnosis Treatment Atrial flutter may cause the following symptoms: Chest pressure or pain Fainting, also known as syncope, or near-syncope Fatigue Lightheadedness[]

  • Atrial Standstill

    Abstract A child with familial atrial standstill and a ventricular pacemaker had syncope due to atrial flutter that was treated by His-bundle ablation.[] Diagnostic criteria of atrial standstill Absent P waves both on surface and intracardiac ECG. Junctional bradycardia.[] This report represents a family with atrial standstill associated with syncope, dilated cardiomyopathy, and sudden cardiac death.[]

  • Familial Atrial Fibrillation

    This disruption in ion transport alters the way the heart beats, increasing the risk of syncope, stroke, and sudden death.[] […] symptoms of familial atrial fibrillation include: Dizziness , Chest pain , a sensation of fluttering or pounding in the chest ( palpitations ), Shortness of breath , fainting ( Syncope[] […] untreated, this abnormal heart rhythm can lead to dizziness, chest pain, a sensation of fluttering or pounding in the chest ( palpitations ), shortness of breath, or fainting ( syncope[]

  • Sinoatrial Block

    However, in cases where dizziness and near syncope due to a sinus node dysfunction are found together with clinical characteristics of a sleep apnea-hypopnea syndrome (SAHS[] There is progressive shortening of the P-P interval, followed by an absent P wave-QRS complex.[] In fact, tachycardia seems to be responsible for the onset of palpitations and heart failure, whereas hypotension, syncope, and weakness arise due to bradycardia.[]

  • Ventricular Tachycardia

    Abstract A 61-year-old male patient was admitted to our hospital with recurrent palpitations and syncope.[] Answers Rhythm: Regular Rate: 150 P Wave: absent PR interval: n/a QRS: Wide and bizarre Interpretation: Ventricular Tachycardia[] Rhythm Regular Rate Fast (100-250 bpm) P Wave Absent PR Interval Not measurable QRS Wide ( 0.10 sec), bizarre appearance Notes[]

  • Bradyarrhythmia

    Syncope may be the presenting symptom in these conditions. However, cocaine-induced bradyarrhythmias have been scarcely mentioned.[] Diagnosis is made via 12 lead EKG and will show an absent P wave, QRS wave and T wave (asystole).[] He complained of syncope which followed convulsions. Their symptoms might be due to circulatory shock caused by a lazy lower pacemaker from the ventricle.[]

  • Electrolyte Imbalance

    Abstract A man presented with recurrent syncope, weakness and fatigue. His ECG showed marked QRS widening and he had gross hyponatraemia and hypokalaemia.[] U waves B. Absent P waves C. Elevated T waves D. Elevated ST segment 57. A. Obtaining a controlled IV infusion pump B. Monitoring urine output during administration C.[] Here, a young woman with prior episodes of auditory stimulus-induced syncope presented with LQTS and ventricular fibrillation (VF) with hypomagnesaemia and hypocalcaemia after[]
