Idaho is No. 3 among states with the most residents experiencing symptoms of lovesickness, which include high levels of stress, high blood pressure and heart palpitations, according to a recent study.

Practice Fusion, a San Francisco firm that analyzes clinical databases, examined more than 2.8 million “de-identified” electronic patient records for the symptoms.

Scientist Jake Marcus said Vermont ranked first on its 2011-12 “love index,” with 32 percent of patients experiencing at least one of the symptoms. Hawaii followed at 28 percent and Idaho at 26 percent.

Based on the firm’s analysis, Idaho had about 122,044 patients suffering from one of the symptoms.

Maryland and North Dakota were the two states with the lowest index for patients experiencing symptoms.
