869 Possible Causes for Low-Voltage Electrocardiogram, Pulsus Paradoxus, Superior Vena Cava Syndrome

  • Chronic Constrictive Pericarditis

    Negative predictors of survival were found to be preoperative NYHA class IV (P 0.01), low-voltage electrocardiogram (ECG) (P 0.01), ascites (P 0.01), dyspnea at rest (P 0.05[] This situation, termed “pulsus paradoxus,” is the classic hallmark of cardiac tamponade.[] The electrocardiogram (Fig. 2) revealed a diphasic T,; T, was inverted. QRS, was of low voltage, and S, was prominent.[]

  • Cardiac Tamponade

    The electrocardiogram showed low-voltage QRS complex with electrical alternans.[] Additionally, there is a case report of tamponade during attempted stent placement in superior vena cava (SVC) syndrome (5).[] Pulsus paradoxus Pulsus paradoxus (or paradoxical pulse) is an exaggeration ( 12 mm Hg or 9%) of the normal inspiratory decrease in systemic blood pressure.[]

  • Hemopericardium

    Local vascular invasion may result in cerebral ischemia, myocardial infarction, and superior vena cava syndrome [ 1 ].[] Other observable signs include rapid heart rate, jugular venous distension, low blood pressure, and pulsus paradoxus.[] A superior vena cava obstruction syndrome may be seen. When dissection involves the distal aorta, it often involves the renal arteries. Urgent repair is required.[]

  • Pulsus Paradoxus

    The electrocardiogram showed sinus tachycardia and low voltage.[] […] venous return Anaphylaxis (see Anaphylaxis, [[Anaphylaxis]]) Superior Vena Cava (SVC) Syndrome (see Superior Vena Cava Syndrome, [[Superior Vena Cava Syndrome]]) Physiology[] When the drop is more than 10 mmHg, it is referred to as pulsus paradoxus.[]

  • Chylopericardium

    We describe a case where superior vena cava syndrome, chylopericardium and chylothorax occurred in a 16-year-old girl due to an indwelling central venous catheter.[] He had pulsus paradoxus with distant heart sounds.[] Percutaneous stenting of SVC has been used with success both in malignant and benign superior vena cava syndrome; however, long-term follow-up of endovascular procedures is[]

  • Chronic Obstructive Pulmonary Disease

    Rationale: Studies evaluating corticosteroid (CS) dosing for patients hospitalized with an acute exacerbation of chronic obstructive pulmonary disease (AECOPD) have largely excluded patients admitted directly to the intensive care unit (ICU), and none have evaluated the effect of CS dosing regimens on mortality.[…][]

  • Pericardial Effusion

    Initial workup will include an electrocardiogram which may show: Low voltage Electric alterans A chest X-ray may show an enlarged globular heart.[] 3.3; 95% CI, 1.8-6.3), while a pulsus paradoxus of 10 mm Hg or less greatly lowers the likelihood (likelihood ratio, 0.03; 95% CI, 0.01-0.24).[] ., patients with clinical signs of tachycardia ( 90 bpm), hypotension (systolic blood pressure 100 mmHg), elevated jugular venous pressure and/or pulsus paradoxus 10 mmHg[]

  • Restrictive Cardiomyopathy

    A low voltage electrocardiogram (ECG) and increased wall thickness with abnormal texture on echocardiography are the classic findings.[] Pulsus paradoxus does not occur.[] We present a 62-year-old with a history of heart failure, which in its assessment highlights the discrepancy between the low voltage ventricular complexes in the electrocardiogram[]

  • Malignant Pericardial Effusion

    This exaggerated fall in systolic blood pressure with inspiration is referred to as pulsus paradoxus.[] Pulsus paradoxus, defined as an inspiratory decrease of more than 10 mmHg in systolic pressure, is a rare but suggestive sign of pericardial effusion.[] She did not have muffled heart sounds, elevated jugular venous pressure (JVP), or pulsus paradoxus.[]

  • Distended Neck Veins

    Superior vena cava syndrome (SVCS) occurs when a person’s superior vena cava is partially blocked or compressed. Cancer is usually the main cause of SVCS.[] paradoxus - Kussmaul's sign - ECHO - IV fluids - pericardiocentesis - open thoracotomy[] Pulsus paradoxus: exaggeration of the normal decrease in systemic blood pressure during inspiration; a pulsus paradoxus greater than 10 mm Hg helps distinguish patients with[]
