“…Some common changes include left axis deviation likely due to displacement of the heart from raised diaphragm due to abdominal visceral fat and small voltages (Eisenstein, Edelstein et al 1982;Frank, Colliver et al 1986;Alpert, Terry et al 2000;Poirier, Giles et al 2006) from the increased distance between the heart and the chest wall (Poirier, Giles et al 2006). Cardiac work load is also increased (Lavie, Milani et al 2009) and this could lead to left ventricular hypertrophy (Lauer, Anderson et al 1991;Poirier, Giles et al 2006;Avelar, Cloward et al 2007;Lavie, Milani et al 2009;Movahed, Martinez et al 2009).…”

“…Pulmonary diseases such as obstructive sleep apnoea could cause cor pulmonale changes. Other possible ECG changes are increased in heart rate (Frank, Colliver et al 1986;Poirier, Giles et al 2006), prolonged PR interval (Frank, Colliver et al 1986;Poirier, Giles et al 2006;Seyfeli, Duru et al 2006), prolonged QRS interval (Frank, Colliver et al 1986;Poirier, Giles et al 2006), prolonged QTc interval (Frank, Colliver et al 1986;Alpert, Terry et al 2000;Pontiroli, Pizzocri et al 2004;Poirier, Giles et al 2006;Arslan, Yiginer et al 2010), ST-T wave abnormalities (Frank, Colliver et al 1986;Poirier, Giles et al 2006) and flattening of the T wave especially in the inferolateral leads (Eisenstein, Edelstein et al 1982;Alpert, Terry et al 2000; Lopez-Jimenez and CortesBergoderi 2011).…”

“…De acordo com estes conceitos, mesmo na ausência de sintomatologia clínica, pacientes obesos necessitam de investigação cardiovascular cuidadosa antes de qualquer cirurgia eletiva. Alterações eletrocardiográficas são comuns em pacientes obesos, como: baixa amplitude do complexo QRS, sobrecarga atrial esquerda, sinais de hipertrofia ventricular esquerda e aumento de átrio esquerdo 19 . Disritmias cardíacas e defeitos na condução podem precipitar morte súbita nos pacientes obesos.…”

“…According to these concepts, even in the absence of clinical symptoms, obese patients need careful cardiovascular evaluation before any elective surgery. ECG abnormalities are common in obese patients, such as: low QRS complex amplitude, left atrial overload, signs of left ventricular hypertrophy and increased left atrium 19 . Arrhythmias and conduction defects may precipitate sudden death in obese patients.…”

“…Embora variáveis eletrocardiográficas como diminuição da voltagem do complexo QRS, taquiarritmias, desvio para a esquerda do eixo e vários critérios para hipertrofia ventricular esquerda (aumento da amplitude da onda R em aVL, da onda S em aVR e da razão R/S em V 1 ) sejam mais freqüentes em obesos "mórbidos" (89), o eletrocardiograma é, porém, extremamente limitado em detectar hipertrofia ventricular e/ou aumento de câmaras cardíacas nesses pacientes, devido à sensibilidade muito baixa (90). O eletrocardiograma de pacientes obesos com hipóxia crônica pode apresentar onda Ppulmonale e desvio do eixo para a direita, secundário à hipertensão pulmonar (91).…”
