53 Possible Causes for Irregular Heart Rhythm, P Wave Absent

  • Atrial Fibrillation

    However, women are more likely to feel their irregular heart rhythm and to have irregular heart beats.[] P waves are absent and replaced by irregular electrical activity. The ventricular rate is irregular and chaotic.[] P waves are absent and replaced by irregular electrical activity. The ventricular rate is irregular and chaotic. Figure 1 Electrocardiogram showing atrial fibrillation.[]

  • Atrial Flutter

    Even people with healthy hearts can have irregular heart rhythms.[] Atypical Aflutter may have varying AV conduction, which can cause an irregular heart rhythm.[] Medications Certain anti-arrhythmic drugs change the electrical signals in the heart and help prevent abnormal sites from starting irregular or rapid heart rhythms.[]

  • Familial Atrial Fibrillation

    The risk of developing this irregular heart rhythm increases with age.[] Atrial fibrillation is the most common type of sustained abnormal heart rhythm ( arrhythmia ), affecting more than 3 million people in the United States .[] ., M.D. [1] Overview Familial atrial fibrillation is an inherited condition that disrupts the heart 's normal rhythm.[]

  • Ventricular Fibrillation

    Ventricular fibrillation: An abnormal and irregular heart rhythm in which there are rapid uncoordinated fluttering contractions of the lower chambers (ventricles) of the heart[] Answers Rhythm: Irregular Rate: Unable to determine P Wave: absent PR interval: absent QRS: absent Interpretation: Ventricular Fibrillation (Fine) Description The morphologic[] Ventricular fibrillation is an abnormally irregular heart rhythm caused by rapid, ineffective, uncoordinated contraction of the ventricles which produce no peripheral pulse[]

  • Atrioventricular Junctional Rhythm

    Racial disparities seen in U.S. heart rhythm treatment (Reuters Health) - Black patients in the U.S. with atrial fibrillation - an irregular heart rhythm - are less likely[] P waves may be present or absent. P waves may not be related to the QRS complexes.[] 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:[]

  • Ventricular Tachycardia

    If left untreated, some forms of ventricular tachycardia may get worse and lead to ventricular fibrillation (fast and irregular heart rhythm), which can be life-threatening[] 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[]

  • Sinoatrial Block

    O'Brien AS CCT CRAT RMA Learning Objectives At the conclusion of this training module the reader will be able to: Recall and apply the 5-steps of heart rhythm interpretation[] There is progressive shortening of the P-P interval, followed by an absent P wave-QRS complex.[] In 3rd-degree SA block, conduction is blocked; P waves are absent, giving the appearance of sinus arrest.[]

  • Electrolyte Imbalance

    heart rhythms.[] 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.[] Electrolytes are needed to keep the body's balance of fluids at the proper level and to maintain normal functions, such as heart rhythm, muscle contraction, and brain function[]

  • Premature Atrial Contractions

    Atrial fibrillation (AF) is one of the most common abnormal or irregular heart rhythms ( arrhythmias ) in the world today.[] In SA block the sinus activity is preserved, but the impulses are blocked resulting in missed P waves and QRS complexes.[] Atrial fibrillation is an irregular heart rhythm characterized by a rapid onset, spontaneous irregular heartbeat. This abnormal heart rhythm could be stimulated by PACs.[]

  • Atrial Standstill

    Abstract A forty-five year old man with longstanding rheumatic heart disease whose surface electrocardiogram (ECG) showed absent P waves and two alternating QRS complex rhythms[] Diagnostic criteria of atrial standstill Absent P waves both on surface and intracardiac ECG. Junctional bradycardia.[] EKG Absent P waves. JVP Absent A waves.[]
