Treatment of sick sinus syndrome in a patient with cardiac lymphoma via chemotherapy without pacemaker implantation: A case report

Figures

• 

  FIGURE 1. Electrocardiogram monitoring at the previous doctor (A). It shows sinus arrest up to 5.4 s and following escape rhythm. After atropine injection and starting continuous intravenous infusion of isoprenaline, the pulse rate was stable at about 70 bpm (B)

• 

  FIGURE 2. Transthoracic echocardiogram of parasternal long‐axis view before chemotherapy (A), on Day3 after start of chemotherapy (B), and on Day 13 (C). A significant reduction of the mass was observed after chemotherapy. LA, left atrium; LV, left ventricle; red arrows: mass

• 

  FIGURE 3. Cardiac contrast CT before chemotherapy, showing the mass involving the superior vena cava, right atrium, left atrium, and left ventricle. Ao, aorta; SVC, superior vena cava; PA, pulmonary artery; RA, right atrium; LA, left atrium; LV, left ventricle, red arrows: mass

• 

  FIGURE 4. PET‐CT before chemotherapy, showing high accumulation in the heart and mild accumulation in the mesenteric lymph node

• 

  FIGURE 5. Histopathological images obtained at autopsy. Infiltration of DLBCL was observed in bone marrow (A), liver (B), and adrenal glands (C). In the sinus node, there was no residual lymphoma and no obvious scarring or fibrosis (D)
