  • Digitalis Toxicity

    The normal features of digitalis toxicity include: delirium, confusion, dizziness, headache, abdominal pain, diarrhea, vomiting, nausea and anorexia.[symptoma.com] bigeminy, and regularized AF.[calsprogram.org] The earliest signs of toxicity in the newborn are undue slowing of the pulse rate (bradycardia), sinoatrial arrest and prolongation of the PR Interval (A Collins Abrams, 2006[rn.com]

DIAGNOSES: The thrombus was confirmed by echocardiography.[ncbi.nlm.nih.gov]

  • Electrolytes Abnormal

    Low calcium may also result in numbness in the extremities as well as confusion and dizziness.[livestrong.com] ECG changes in patients with hyperkalemia are progressive and include peaked T waves, flattened P waves, prolonged PR interval, widened QRS complex, and, finally, a sine wave[musculoskeletalkey.com] […] shortening, prolongation of PR 15 mg/dL – heart block, cardiac arrest Etiologies Cancer with bone metastasis (in particular prostate and breast ) Hyperparathyroidism, thyrotoxicosis[arupconsult.com]

  • Acute Myocarditis

    Two patients (aged 46 and 49 years) are presented who gave a history of several years' duration of unsteadiness, dizziness, and syncopal attacks on standing.[ncbi.nlm.nih.gov] RVOT non-sustained monomorphic ventricular tachycardia (on the left side) and LVOT ventricular bigeminy (on the right side). Figure 2.[escardio.org] ) this AV nodal conduction delay is manifested by a prolonged PR interval on the surface ECG.[af-ablation.org]

  • Premature Atrial Contractions

    Then 2 weeks ago I had to call 911, my heartrate was extremely fast and I was dizzy and very sick. Recommended[healthquestions.medhelp.org] This results in the premature beat displaying a right bundle branch block pattern and can be confused with a premature ventricular contraction.[healio.com] However, PR variation and prolonged PR interval were not associated with all-cause mortality (P   0.465 and 0.774, respectively).PR interval variation and prolonged PR interval[ncbi.nlm.nih.gov]

  • Ventricular Bigeminy

    Warning signs would be if the skipping persisted for many minutes, or you felt dizzy, lightheaded, short of breath of chest pains.[healthtap.com] Ventricular bigeminy can develop following a cobra envenomation.[ncbi.nlm.nih.gov] They may be followed either by a normal QRS complex, or the PR interval may be prolonged, or the impulse may not be conducted at all.[patient.info]
