How it works / reminders

• Uses E/e' septal and/or E/e' lateral from your inputs.
• Lateral: normal < 8; elevated > 12; 8-12 indeterminate.
• Septal: normal < 8; elevated > 15; 8-15 indeterminate.
• Normal EF (>= 50%): low E/e' can support normal filling; elevated E/e' supports elevated filling.
• Reduced EF (< 50%): elevated E/e' supports elevated filling; low/normal E/e' does not exclude elevated filling.
• Formal grading needs LA volume index and TR velocity.
